Summary:
Added nhwc support for:
1. cudnn_batch_norm & cudnn_batch_norm_backward
2. cudnn_convolution_forward & cudnn_convolution_backward
3. cudnn_convolution_transpose & cudnn_convolution_transpose_backward
patching suggest_memory_format for convolution
suggest_memory_format has ambiguous meaning for two cases:
1. tensor with NCHW where C = 1.
we could use stride of C as a hint to tell the intended memory format.
2. tensor with NCHW where H == W == 1.
there's no way to identify the intended memory format from strides.
Currently we fallback to NCHW whenever we see contiguous tensor. Hence avoiding
ambiguity for some of the special cases.

This is an attempt to fix _empty_per_channel_affine_quantized to be more sane. It's a factory function that nevertheless receives a Tensor argument and it throws the codegen off course.
Before people did a hacky workaround of appending _like to the function name to trick codegen, it also required non-natural argument order.
This PR explicitly allows to override the 'category' of the function to make codegen do the right thing. Now name and the argument order (in C++) make more sense.

Summary:
Follow-up to gh-25483, more of the same fixes for warnings like:
```
../torch/csrc/autograd/python_variable.cpp:503:31: warning: cast between incompatible function types from ‘PyObject* (*)(THPVariable*)’ {aka ‘_object* (*)(THPVariable*)’} to ‘getter’ {aka ‘_object* (*)(_object*, void*)’} [-Wcast-function-type]
503 | {"_backward_hooks", (getter)THPVariable_get_backwards_hooks, (setter)THPVariable_set_backwards_hooks, nullptr, nullptr},
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
```
This takes the build log output for a full rebuild with GCC 9.1 from ~10,000 to ~7,000 lines.
`clang-tidy` is going to complain, no way around that - see discussion at the end of gh-25483.

Pull Request resolved: https://github.com/pytorch/pytorch/pull/25475
I got sucked into this rabbit hole when I was trying to understand
what I should do with TensorTypeId occurrences in
torch/csrc/utils/tensor_new.cpp. I eventually concluded that all of my problems
were because Tensor.new_empty was hand implemented and not actually a native
function. So I made it a native function.
There are a bunch of other new_* functions which should get this
treatment, but I'm sending out this PR just to show how it can
be done.
The general recipe:
1. Implement a concept of TensorOptions merging (TensorOptions::merge_in).
This represents the notion of taking a tensor, but "overriding" some
of its values with specific overrides. One subtlety here is how
devices get merged; see the comments for what our existing behavior is,
and how I preserve it.
2. Implement new_empty as a native function, using options merging.
3. Add another special case to Python binding generation to treat new_*
similar to *_like (i.e., handle TensorOptions correctly). The logic
here is probably wrong, actually; we should codegen TensorOptions
correctly no matter what happens, but new_empty follows the same
pattern as empty_like so I opted not to touch this code too much.
4. Delete the now defunct manual binding code.
5. Delete manual type annotations that are no longer necessary since
we're going through native.
I didn't handle memory format correctly here. I don't know if this function
should accept memory format; prior memory format patches didn't add support
for memory format to new_like. If we had put memory format in TensorOptions
this wouldn't have been a question.

This change is backwards incompatible in *C++ only* on mean(), sum(), and prod() interfaces that accepted either of:
```
Tensor sum(IntArrayRef dim, bool keepdim=false) const;
Tensor sum(IntArrayRef dim, ScalarType dtype) const;
```
but now to specify both the dim and dtype will require the keepdim parameter:
```
Tensor sum(IntArrayRef dim, bool keepdim=false, c10::optional<ScalarType> dtype=c10::nullopt) const;
```

Summary:
Something flaky is going on with `test_inplace_view_saved_output` on Windows.
With my PR #20598 applied, the test fails, even though there is no obvious reason it should be related, so the PR was reverted.
Based on commenting out various parts of my change and re-building, I think the problem is with the name -- renaming everything from `T` to `asdf` seems to make the test stop failing. I can't be sure that this is actually the case though, since I could just be seeing patterns in non-deterministic build output...
I spoke with colesbury offline and we agreed that it is okay to just disable this test on Windows for now and not block landing the main change. He will look into why it is failing.
**Test Plan:** I will wait to make sure the Windows CI suite passes before landing this.

Summary:
in functional interfaces we do boolean dispatch, but all to max_pool\*d_with_indices. This change it to emit max_pool\*d op instead when it's not necessary to expose with_indices ops to different backends (for jit).
It also bind max_pool\*d to the torch namespace, which is the same behavior with avg_pool\*d

Summary:
Make it possible to construct a pinned memory tensor without creating a storage first and without calling pin_memory() function. It is also faster, as copy operation is unnecessary.
Supported functions:
```python
torch.rand_like(t, pin_memory=True)
torch.randn_like(t, pin_memory=True)
torch.empty_like(t, pin_memory=True)
torch.full_like(t, 4, pin_memory=True)
torch.zeros_like(t, pin_memory=True)
torch.ones_like(t, pin_memory=True)
torch.tensor([10,11], pin_memory=True)
torch.randn(3, 5, pin_memory=True)
torch.rand(3, pin_memory=True)
torch.zeros(3, pin_memory=True)
torch.randperm(3, pin_memory=True)
torch.empty(6, pin_memory=True)
torch.ones(6, pin_memory=True)
torch.eye(6, pin_memory=True)
torch.arange(3, 5, pin_memory=True)
```
Part of the bigger: `Remove Storage` plan.
Now compatible with both torch scripts:
` _1 = torch.zeros([10], dtype=6, layout=0, device=torch.device("cpu"), pin_memory=False)`
and
` _1 = torch.zeros([10], dtype=6, layout=0, device=torch.device("cpu"))`
Same checked for all similar functions `rand_like`, `empty_like` and others
It is fixed version of #18455

Summary:
Changelog:
- Renames `btrifact` and `btrifact_with_info` to `lu`to remain consistent with other factorization methods (`qr` and `svd`).
- Now, we will only have one function and methods named `lu`, which performs `lu` decomposition. This function takes a get_infos kwarg, which when set to True includes a infos tensor in the tuple.
- Rename all tests, fix callsites
- Create a tentative alias for `lu` under the name `btrifact` and `btrifact_with_info`, and add a deprecation warning to not promote usage.
- Add the single batch version for `lu` so that users don't have to unsqueeze and squeeze for a single square matrix (see changes in determinant computation in `LinearAlgebra.cpp`)
