This PR heavily simplifies the code of `linalg.solve`. At the same time,
this implementation saves quite a few copies of the input data in some
cases (e.g. A is contiguous)
We also implement it in such a way that the derivative goes from
computing two LU decompositions and two LU solves to no LU
decompositions and one LU solves. It also avoids a number of unnecessary
copies the derivative was unnecessarily performing (at least the copy of
two matrices).
On top of this, we add a `left` kw-only arg that allows the user to
solve `XA = B` rather concisely.

Adds:
```Python

```
Chebyshev polynomial of the first kind $T_{n}(\text{input})$.
If $n = 0$, $1$ is returned. If $n = 1$, $\text{input}$ is returned. If $n < 6$ or $|\text{input}| > 1$ the recursion:
$$T_{n + 1}(\text{input}) = 2 \times \text{input} \times T_{n}(\text{input}) - T_{n - 1}(\text{input})$$
is evaluated. Otherwise, the explicit trigonometric formula:
$$T_{n}(\text{input}) = \text{cos}(n \times \text{arccos}(x))$$
is evaluated.
## Derivatives
Recommended $k$-derivative formula with respect to $\text{input}$:
$$2^{-1 + k} \times n \times \Gamma(k) \times C_{-k + n}^{k}(\text{input})$$
where $C$ is the Gegenbauer polynomial.
Recommended $k$-derivative formula with respect to $\text{n}$:
$$\text{arccos}(\text{input})^{k} \times \text{cos}(\frac{k \times \pi}{2} + n \times \text{arccos}(\text{input})).$$

This PR modifies `lu_unpack` by:
- Using less memory when unpacking `L` and `U`
- Fuse the subtraction by `-1` with `unpack_pivots_stub`
- Define tensors of the correct types to avoid copies
- Port `lu_unpack` to be a strucutred kernel so that its `_out` version
does not incur on extra copies
Then we implement `linalg.lu` as a structured kernel, as we want to
compute its derivative manually. We do so because composing the
derivatives of `torch.lu_factor` and `torch.lu_unpack` would be less efficient.
This new function and `lu_unpack` comes with all the things it can come:
forward and backward ad, decent docs, correctness tests, OpInfo, complex support,
support for metatensors and support for vmap and vmap over the gradients.
I really hope we don't continue adding more features.
This PR also avoids saving some of the tensors that were previously
saved unnecessarily for the backward in `lu_factor_ex_backward` and
`lu_backward` and does some other general improvements here and there
to the forward and backward AD formulae of other related functions.

The result of `torch.linalg.ldl_factor_ex` is in a compact form and it's required to use it only through `torch.linalg.ldl_solve`. In the future, we could provide `ldl_unpack` function that transforms the compact representation into explicit matrices.

I've hit a lot of build issues in D32671972, and I've come to realize that a lot of it boils down to header hygene. `function.h` includes `profiler.h` *solely* to transitively include `record_function.h` which winds up leaking the profiler symbols. Moreover several files are relying on transitive includes to get access to `getTime`. As long as I have to touch all the places that use `getTime`, I may as well also move them to the new namespace.

This PR adds the first solver with structure to `linalg`. This solver
has an API compatible with that of `linalg.solve` preparing these for a
possible future merge of the APIs. The new API:
- Just returns the solution, rather than the solution and a copy of `A`
- Removes the confusing `transpose` argument and replaces it by a
correct handling of conj and strides within the call
- Adds a `left=True` kwarg. This can be achieved via transposes of the
inputs and the result, but it's exposed for convenience.
This PR also implements a dataflow that minimises the number of copies
needed before calling LAPACK / MAGMA / cuBLAS and takes advantage of the
conjugate and neg bits.
This algorithm is implemented for `solve_triangular` (which, for this, is
the most complex of all the solvers due to the `upper` parameters).
Once more solvers are added, we will factor out this calling algorithm,
so that all of them can take advantage of it.
Given the complexity of this algorithm, we implement some thorough
testing. We also added tests for all the backends, which was not done
before.
We also add forward AD support for `linalg.solve_triangular` and improve the
docs of `linalg.solve_triangular`. We also fix a few issues with those of
`torch.triangular_solve`.

This makes Tensor inherit from a new class TensorBase, that provides a subset of Tensor that doesn't
directly depend on native_functions.yaml. Code that only includes TensorBase.h with thus not need to
be rebuilt every time someone changes an operator signature.
Making `Tensor` inherit from this class means that `const TensorBase&` parameters will be callable
with an ordinary `Tensor`. I've also made `Tensor` constructible and assignable from `TensorBase` to
minimize friction in code mixing the two types.
To help enforce that `Tensor.h` and `Functions.h` aren't accidentally included, I've added an error
into `Operators.h` if `TORCH_ASSERT_NO_OPERATORS` is defined. We can either set this in the build
system for certain folders, or just define it at the top of any file.
I've also included an example of manually special-casing the commonly used `contiguous` operator.
The inline function's slow path defers to `TensorBase::__dispatch_contiguous` which is defined in
`Tensor.cpp`. I've made it so `OptionalTensorRef` is constructible from `TensorBase`, so I can
materialize a `Tensor` for use in dispatch without actually increasing its refcount.

### Changes
Per the discussion in the above issue, this PR makes 2 changes:
1. When `error_if_nonfinite=False`, the NaN/Inf checks are truly skipped, and no device synchronization occurs.
- Additionally, when performing the checks, the 2 results are combined with `torch.logical_or` to incur only a single sync (instead of 2 in the happy/finite path).
2. The `clip_coef` conditional is removed, in favor of a call to `clamp(..., max=1.0)` and an unconditional multiplication.
### Testing
- The existing unit tests for `clip_grad_norm_` pass.
- I have manually profiled the example program from https://github.com/pytorch/pytorch/issues/60691, and verified that:
- No synchronizations occur when using `error_if_nonfinite=False`.
- A single synchronization occurs when using `error_if_nonfinite=True`.

Summary:
Reference https://github.com/pytorch/pytorch/issues/50345
`zeta` was already present in the codebase to support computation of `polygamma`.
However, `zeta` only had `double(double, double)` signature **for CPU** before the PR (which meant that computation `polygamma` were always upcasted to `double` for zeta part).
With this PR, float computations will take place in float and double in double.
Have also refactored the code and moved the duplicate code from `Math.cuh` to `Math.h`
**Note**: For scipy, q is optional, and if it is `None`, it defaults `1` which corresponds to Reimann-Zeta. However, for `torch.specia.zeta`, I made it mandatory cause for me it feels odd without `q` this is Reimann-Zeta and with `q` it is the general Hurwitz Zeta. I think sticking to just general made more sense as passing `1` for q sounds trivial.

Summary:
This PR is focused on the API for `linalg.matrix_norm` and delegates computations to `linalg.norm` for the moment.
The main difference between the norms is when `dim=None`. In this case
- `linalg.norm` will compute a vector norm on the flattened input if `ord=None`, otherwise it requires the input to be either 1D or 2D in order to disambiguate between vector and matrix norm
- `linalg.vector_norm` will flatten the input
- `linalg.matrix_norm` will compute the norm over the last two dimensions, treating the input as batch of matrices
In future PRs, the computations will be moved to `torch.linalg.matrix_norm` and `torch.norm` and `torch.linalg.norm` will delegate computations to either `linalg.vector_norm` or `linalg.matrix_norm` based on the arguments provided.

Note that we cannot remove the optional type from the `dim` parameter because the default is to flatten the input tensor which cannot be easily captured by a value other than `None`
### BC Breaking Note
This PR changes the `ord` parameter of `torch.linalg.vector_norm` so that it no longer accepts `None` arguments. The default behavior of `2` is equivalent to the previous default of `None`.

This adds [breakpad](https://github.com/google/breakpad) which comes with out-of-the-box utilities to register a signal handler that writes out a minidump on an unhandled exception. Right now this is gated behind a flag in `torch.utils`, but in the future it could be on by default. Sizewise this adds aboute 500k to `libtorch_cpu.so` (187275968 B to 187810016 B).
```bash
$ cat <<EOF > test.py
import torch
torch.utils.enable_minidump_collection()
# temporary util that just segfaults
torch._C._crash()
EOF
$ python test.py
Wrote minidump to /tmp/pytorch_crashes/6a829041-50e9-4247-ea992f99-a74cf47a.dmp
fish: “python test.py” terminated by signal SIGSEGV (Address boundary error)
$ minidump-2-core /tmp/pytorch_crashes/6a829041-50e9-4247-ea992f99-a74cf47a.dmp -o core.dmp
$ gdb python core.dmp
... commence debugging ...
```
Right now all exceptions that get passed up to Python don't trigger the signal handler (which by default only
handles [these](https://github.com/google/breakpad/blob/main/src/client/linux/handler/exception_handler.cc#L115)). It would be possible for PyTorch exceptions to explicitly write a minidump when passed up to Python (maybe only when the exception is unhandled or something).

Summary:
This PR adds `torch.linalg.eig`, and `torch.linalg.eigvals` for NumPy compatibility.
MAGMA uses a hybrid CPU-GPU algorithm and doesn't have a GPU interface for the non-symmetric eigendecomposition. It means that it forces us to transfer inputs living in GPU memory to CPU first before calling MAGMA, and then transfer results from MAGMA to CPU. That is rather slow for smaller matrices and MAGMA is faster than CPU path only for matrices larger than 3000x3000.
Unfortunately, there is no cuSOLVER function for this operation.
Autograd support for `torch.linalg.eig` will be added in a follow-up PR.

First part of #3867 (Pooling operators still to do)
This adds a `padding='same'` mode to the interface of `conv{n}d`and `nn.Conv{n}d`. This should match the behaviour of `tensorflow`. I couldn't find it explicitly documented but through experimentation I found `tensorflow` returns the shape `ceil(len/stride)` and always adds any extra asymmetric padding onto the right side of the input.
Since the `native_functions.yaml` schema doesn't seem to support strings or enums, I've moved the function interface into python and it now dispatches between the numerically padded `conv{n}d` and the `_conv{n}d_same` variant. Underscores because I couldn't see any way to avoid exporting a function into the `torch` namespace.
A note on asymmetric padding. The total padding required can be odd if both the kernel-length is even and the dilation is odd. mkldnn has native support for asymmetric padding, so there is no overhead there, but for other backends I resort to padding the input tensor by 1 on the right hand side to make the remaining padding symmetrical. In these cases, I use `TORCH_WARN_ONCE` to notify the user of the performance implications.

Since `torch.orgqr` is one of few functions that expose LAPACK's naming and all other linear algebra routines were renamed a long time ago, I also added a new function with a new name and `torch.orgqr` now is an alias for it.
The new proposed name is `householder_product`. For a matrix `input` and a vector `tau` LAPACK's orgqr operation takes columns of `input` (called Householder vectors or elementary reflectors) scalars of `tau` that together represent Householder matrices and then the product of these matrices is computed. See https://www.netlib.org/lapack/lug/node128.html.
Other linear algebra libraries that I'm aware of do not expose this LAPACK function, so there is some freedom in naming it. It is usually used internally only for QR decomposition, but can be useful for deep learning tasks now when it supports differentiation.

Summary:

`Scalar` takes 32 bytes due to `c10::complex<double>`
requires aligning to 16 bytes. Passing Scalar by reference
shows about 1% improvements on instruction count.
All the changes in this commit are codemoded except for
the following 4 files (which code-gen signatures):
```
tools/codegen/api/cpp.py
tools/codegen/api/native.py
tools/codegen/api/structured.py
caffe2/contrib/aten/gen_op.py
```
# Codemode
## Main Step
For the codemod part, here is the main command used:
```
fastmod --extensions h '([a-zA-Z_+]\([^)]*,?\s*)Scalar (\w+)' '${1}const Scalar& ${2}'
fastmod --extensions h '([a-zA-Z_+]\([^)]*,?\s*)optional<Scalar> (\w+)' '${1}const optional<Scalar>& ${2}'
fastmod --extensions cpp '([a-zA-Z_+]\([^)]*,?\s*)Scalar (\w+)' '${1}const Scalar& ${2}'
fastmod --extensions cpp '([a-zA-Z_+]\([^)]*,?\s*)optional<Scalar> (\w+)' '${1}const optional<Scalar>& ${2}'
```
As you can tell, it codemods both `Scalar` and `optional<Scalar>`. Apply these commands iteratively until reaching a fix-point (since one method signature might contain multiple `Scalar` parameter).
In retrospect, excluding `thrid_party` and `torch/csrc/jit` would be a good idea. (I revert it manually later, see https://github.com/pytorch/pytorch/pull/53479 as an reference).
## Pre-Step
Prior to applying the main command, as some `Scalar` are presented as `at::Scalar` or `c10::Scalar`, so I codemod some of them in advance. Here is an incomplete list:
```
fastmod --extensions h '([a-zA-Z_+]\([^)]*,?\s*)at::Scalar (\w+)' '${1}const at::Scalar& ${2}'
fastmod --extensions cpp '([a-zA-Z_+]\([^)]*,?\s*)at::Scalar (\w+)' '${1}const at::Scalar& ${2}'
fastmod --extensions h '([a-zA-Z_+]\([^)]*,?\s*)c10::optional<Scalar> (\w+)' '${1}const c10::optional<Scalar>& ${2}'
fastmod --extensions cpp '([a-zA-Z_+]\([^)]*,?\s*)c10::optional<Scalar> (\w+)' '${1}const c10::optional<Scalar>& ${2}'
```
## Fixup
There are a couple of post codemod fixup. For example, `const Scalar` will be codemoded into `const const Scalar&`. `at:Scalar` will be codemoded into `at::const Scalar&` (if `Pre-step` is not done comprehensively). Here is an incomplete list:
```
fastmod --extensions cpp 'const const Scalar' 'const Scalar'
fastmod --extensions h 'const const c10::optional<Scalar>' 'const c10::optional<Scalar>'
fastmod --extensions cpp 'const const c10::optional<Scalar>' 'const c10::optional<Scalar>'
fastmod 'at::const Scalar&' 'const at::Scalar&'
```
## Supplementary
`cu` and `mm` files also need to be codemoded, for example:
```
fastmod --extensions cu 'at::const Scalar&' 'const at::Scalar&'
fastmod --extensions mm '([a-zA-Z_+]\([^)]*,?\s*)Scalar (\w+)' '${1}const Scalar& ${2}'
```
Function pointers are not codemoded. Here is an incomplete list:
```
# Cover case: using index_fill_fn = void(*)(TensorIterator & iter, int64_t dim, int64_t self_dim_size, int64_t self_dim_stride, Scalar source);
fastmod --extensions h '(void\s*\(\s*\*\s*\)\([^)]*,?\s*)Scalar (\w+)' '${1}const Scalar& ${2}'
# Cover case: using softplus_fn = void (*)(TensorIterator&, Scalar, Scalar);
fastmod --extensions h '(void\s*\(\s*\*\s*\)\([^)]*,?\s*)Scalar([, \)])' '${1}const Scalar&${2}'
fastmod --extensions cpp '(void\s*\(\s*\*\s*\)\([^)]*,?\s*)Scalar([, \)])' '${1}const Scalar&${2}'
fastmod --extensions h '(void\s*\(\s*\*\s*\)\([^)]*,?\s*)optional<Scalar>([, \)])' '${1}const optional<Scalar>&${2}'
```
Some corner cases needs to be manually fixed.

Summary:
Fixes https://github.com/pytorch/pytorch/issues/46213
I didn't yet update the documentation, will add those change soon. A few other things that I didn't do, but want to clarify if I maybe should.
1. I didn't expose projections in c++ API: torch/csrc/api/src/nn/modules/rnn.cpp. Let me know if this is desirable and I will add those changes.
2. I didn't expose projections in "lstm_cell" function and "_thnn_differentiable_lstm_cell_backward" functions from aten/src/ATen/native/RNN.cpp. As far as I understand, they are not needed for nn.LSTM CPU execution. For lstm_cell, projections don't bring any real benefit, since if cell is used separately, it can be easily added in Python. For "_thnn_differentiable_lstm_cell_backward", I'm actually not sure where exactly that function is used, so I also disabled projections there for now. Please let me know if I should change that.
3. I added check that projections are not supported for quantized LSTMs to quantized_lstm_<data/input> functions. But I didn't add any checks to LSTMCell code. It seems that since I disabled projections in "lstm_cell" function, they should also not be available for quantized models through any other API than quantized_lstm_<data/input>. Please let me know if I'm not correct and I will add checks to other places.
4. Projections are not supported for CuDNN versions < 7.1.2. Should I add the check for CuDNN version and disable projections in that case? If so, what will be the best way to do that?
5. Currently I added projection weight as the last weight, so the layout is "w_ih, w_hh, b_ih, b_hh, w_hr". This breaks the assumption that biases come after weights and thus I had to add additional if-s in various places. Alternative way would be to have "w_ih, w_hh, w_hr, b_ih, b_hh" layout, in which case the assumption will be true. But in that case I will need to split the loop in get_parameters function from aten/src/ATen/native/cudnn/RNN.cpp. And in some cases, I will still need to add an "undefined" tensor in the 3rd position, because we get all 5 weights from CuDNN most of the time. So I'm not sure which way is better. Let me know if you think I should change to the weights-then-biases layout.

Changes compared to the original `torch.matrix_rank`:

Should I update the documentation for `torch.matrix_rank`?
For the input with no elements (for example 0×0 matrix), the current implementation is divergent from NumPy. NumPy stumbles on not defined max for such input, here I chose to return appropriately sized tensor of zeros. I think that's mathematically a correct thing to do.

I added bicubic grid sampler in both cpu and cuda side, but haven't in AVX2
There is a [colab notebook](https://colab.research.google.com/drive/1mIh6TLLj5WWM_NcmKDRvY5Gltbb781oU?usp=sharing) show some test results. The notebook use bilinear for test, since I could only use distributed version of pytorch in it. You could just download it and modify the `mode_torch=bicubic` to show the results.
There are some duplicate code about getting and setting values, since the helper function used in bilinear at first clip the coordinate beyond boundary, and then get or set the value. However, in bicubic, there are more points should be consider. I could refactor that part after making sure the overall calculation are correct.

This PR implements `fft2`, `ifft2`, `rfft2` and `irfft2`. These are the last functions required for `torch.fft` to match `numpy.fft`. If you look at either NumPy or SciPy you'll see that the 2-dimensional variants are identical to `*fftn` in every way, except for the default value of `axes`. In fact you can even use `fft2` to do general n-dimensional transforms.

Part of the `torch.fft` work (gh-42175).
This adds n-dimensional transforms: `fftn`, `ifftn`, `rfftn` and `irfftn`.
This is aiming for correctness first, with the implementation on top of the existing `_fft_with_size` restrictions. I plan to follow up later with a more efficient rewrite that makes `_fft_with_size` work with arbitrary numbers of dimensions.

Summary:
This PR:
- updates test_op_normalization.py, which verifies that aliases are correctly translated in the JIT
- adds torch.linalg.det as an alias for torch.det
- moves the torch.linalg.outer alias to torch.outer (to be consistent with NumPy)
The torch.linalg.outer alias was put the linalg namespace erroneously as a placeholder since it's a "linear algebra op" according to NumPy but is actually still in the main NumPy namespace.
The updates to test_op_normalization are necessary. Previously it was using method_tests to generate tests, and method_tests assumes test suites using it also use the device generic framework, which test_op_normalization did not. For example, some ops require decorators like `skipCPUIfNoLapack`, which only works in device generic test classes. Moving test_op_normalization to the device generic framework also lets these tests run on CPU and CUDA.
Continued reliance on method_tests() is excessive since the test suite is only interested in testing aliasing, and a simpler and more readable `AliasInfo` class is used for the required information. An example impedance mismatch between method_tests and the new tests, for example, was how to handle ops in namespaces like torch.linalg.det. In the future this information will likely be folded into a common 'OpInfo' registry in the test suite.
The actual tests performed are similar to what they were previously: a scripted and traced version of the op is run and the test verifies that both graphs do not contain the alias name and do contain the aliased name.
The guidance for adding an alias has been updated accordingly.

Note:
ngimel suggests:
- deprecating and then removing the `torch.ger` name
- reviewing the implementation of `torch.outer`

Summary:
This PR adds the `torch.linalg` namespace as part of our continued effort to be more compatible with NumPy. The namespace is tested by adding a single function, `torch.linalg.outer`, and testing it in a new test suite, test_linalg.py. It follows the same pattern that https://github.com/pytorch/pytorch/pull/41911, which added the `torch.fft` namespace, did.
Future PRs will likely:
- add more functions to torch.linalg
- expand the testing done in test_linalg.py, including legacy functions, like torch.ger
- deprecate existing linalg functions outside of `torch.linalg` in preference to the new namespace

Summary:
This PR creates a new namespace, torch.fft (torch::fft) and puts a single function, fft, in it. This function is analogous to is a simplified version of NumPy's [numpy.fft.fft](https://numpy.org/doc/1.18/reference/generated/numpy.fft.fft.html?highlight=fft#numpy.fft.fft) that accepts no optional arguments. It is intended to demonstrate how to add and document functions in the namespace, and is not intended to deprecate the existing torch.fft function.
Adding this namespace was complicated by the existence of the torch.fft function in Python. Creating a torch.fft Python module makes this name ambiguous: does it refer to a function or module? If the JIT didn't exist, a solution to this problem would have been to make torch.fft refer to a callable class that mimicked both the function and module. The JIT, however, cannot understand this pattern. As a workaround it's required to explicitly `import torch.fft` to access the torch.fft.fft function in Python:
```
import torch.fft
t = torch.randn(128, dtype=torch.cdouble)
torch.fft.fft(t)
```
See https://github.com/pytorch/pytorch/issues/42175 for future work. Another possible future PR is to get the JIT to understand torch.fft as a callable class so it need not be imported explicitly to be used.

xref gh-38010 and gh-38011.
After this PR, there should be only two warnings:
```
pytorch/docs/source/index.rst:65: WARNING: toctree contains reference to nonexisting \
document 'torchvision/index'
WARNING: autodoc: failed to import class 'tensorboard.writer.SummaryWriter' from module \
'torch.utils'; the following exception was raised:
No module named 'tensorboard'
```
If tensorboard and torchvision are prerequisites to building docs, they should be added to the `requirements.txt`.
As for breaking up quantization into smaller pieces: I split out the list of supported operations and the list of modules to separate documents. I think this makes the page flow better, makes it much "lighter" in terms of page cost, and also removes some warnings since the same class names appear in multiple sub-modules.

Summary:
Update the API to access grad in cpp to avoid unexpected thread safety issues.
In particular, with the current API, a check like `t.grad().defined()` is not thread safe.
- This introduces `t.mutable_grad()` that should be used when getting a mutable version of the saved gradient. This function is **not** thread safe.
- The `Tensor& grad()` API is now removed. We could not do a deprecation cycle as most of our call side use non-const Tensors that use the non-const overload. This would lead to most calls hitting the warning. This would be too verbose for all the users.

Summary:
BCELoss currently uses different broadcasting semantics than numpy. Since previous versions of PyTorch have thrown a warning in these cases telling the user that input sizes should match, and since the CUDA and CPU results differ when sizes do not match, it makes sense to upgrade the size mismatch warning to an error.
We can consider supporting numpy broadcasting semantics in BCELoss in the future if needed.

I had a problem with another test though (see commit c1a6241676ab84fc531c1c3a10f964aa5704092e), it seems that optimizing for two steps with the same optimizer vs optimizing for two steps using freshly initialized objects will produce the same output.

These changes were all done manually, and I skipped anything that seemed
like it would take more than a few seconds, so I think it makes sense to
review it manually as well.
