Summary:
Fixes https://github.com/pytorch/pytorch/issues/63341.
This PR adds a new test, `test_noncontigous_samples`, that runs ops forward and backward and compares their outputs and grads between "normal" contiguous SampleInputs and noncontiguous SampleInputs. This test should preclude the need for noncontiguous SampleInputs going forward.
The test was added by generalizing the `.numpy()` transform on SampleInputs to support a new `.noncontiguous()` transform and copying forward/backward patterns from other tests in test_ops.py. It also discovered that many SampleInputs were incorrectly reusing tensors, so those have been revised. SampleInputs creating noncontiguous tensors for testing have also been altered to no longer do so.
In addition, this test discovered the following high priority silent correctness issues:
- https://github.com/pytorch/pytorch/issues/67432
- https://github.com/pytorch/pytorch/issues/67517
- https://github.com/pytorch/pytorch/issues/67513
- https://github.com/pytorch/pytorch/issues/67512
- https://github.com/pytorch/pytorch/issues/67470
It also identified the following issues:
- https://github.com/pytorch/pytorch/issues/67539
The pow OpInfo also incorrectly specified that pow supported the bool datatype, and this has been fixed. Its SampleInputs were written in a way that made requests for boolean SampleInputs return type promoting inputs that never actually tried to compute pow in bool.
This PR suggests we should add the following guidance for writing SampleInputs:
- ensure that all SampleInputs are independent of each other (don't reuse tensors)
- ensure that all SampleInput tensors have no grad or backward functions (no autograd history) -- they should be leaves
- prefer keeping sample inputs simple where possible, a good set of handwritten samples that test interesting cases may be better than an exhaustive but hard to read and maintain programmatic enumeration
- keep code readable by using functools.partial and writing simple inline helpers; break up large statements into a more readable series of smaller statements; especially don't write complicated generator expressions with a `for` at the end!

Summary:
CAFFE2 has been deprecated for a while, but still included in every PyTorch build.
We should stop building it by default, although CI should still validate that caffe2 code is buildable.
Build even fewer dependencies when compiling mobile builds without Caffe2
Introduce `TEST_CAFFE2` in torch.common.utils
Skip `TestQuantizedEmbeddingOps` and `TestJit.test_old_models_bc` is code is compiled without Caffe2
Should be landed after https://github.com/pytorch/builder/pull/864

Summary:
Fixes https://github.com/pytorch/pytorch/issues/62533.
In very rare cases, the decorator for detecting memory leak is throwing assertion, even when the test is passing, and the memory is being freed with a tiny delay. The issue is not being reproduced in internal testing, but shows up sometimes in CI environment.
Reducing the severity of such detection to warning, so as not to fail the CI tests, as the actual test is not failing, rather only the check inside the decorator is failing.
Limiting the change to ROCM only for now.

Remove dtype tracking from Python Storage interface, remove all the different `<type>Storage` classes except for `ByteStorage`, and update serialization accordingly, while maintaining as much FC/BC as possible
Fixes https://github.com/pytorch/pytorch/issues/47442
* **THE SERIALIZATION FORMAT IS FULLY FC/BC.** We worked very hard to make sure this is the case. We will probably want to break FC at some point to make the serialization structure of tensors make more sense, but not today.
* There is now only a single torch.ByteStorage class. Methods like `Tensor.set_` no longer check that the dtype of storage is appropriate.
* As we no longer know what dtype of a storage is, we've **removed** the size method from Storage, replacing it with nbytes. This is to help catch otherwise silent errors where you confuse number of elements with number of bytes.
* `Storage._new_shared` takes a `nbytes` kwarg and will reject previous positional only calls. `Storage._new_with_file` and `_set_from_file` require explicit element size arguments.
* It's no longer possible to convert storages to different types using the float/double/etc methods. Instead, do the conversion using a tensor.
* It's no longer possible to allocate a typed storage directly using FloatStorage/DoubleStorage/etc constructors. Instead, construct a tensor and extract its storage. The classes still exist but they are used purely for unpickling.
* The preexisting serialization format stores dtype with storage, and in fact this dtype is used to determine the dtype of the tensor overall.
To accommodate this case, we introduce a new TypedStorage concept that exists only during unpickling time which is used to temporarily store the dtype so we can construct a tensor. **If you overrode the handling of pickling/unpickling, you MUST add handling for TypedStorage** or your serialization code will degrade to standard file-based serialization.

Summary:
- Added 2D-Convolution NHWC support
- on ROCm 4.3, with `PYTORCH_MIOPEN_SUGGEST_NHWC=1` flag
- May need to force MIOpen to search for solutions ( see examples below for flags )
**PYTORCH_MIOPEN_SUGGEST_NHWC Environment Flag**
MIOpen does not officially support NHWC yet, although convolution support has been added to tip-of-tree of MIOpen. This flag is intended to be a short-lived flag to explicitly turn on NHWC support until ROCm officially supports NHWC and performance is verified.
**Examples**
1. Example usage 1 : Run test on ROCm4.3
`PYTORCH_TEST_WITH_ROCM=1 PYTORCH_MIOPEN_SUGGEST_NHWC=1 MIOPEN_FIND_ENFORCE=4 MIOPEN_DEBUG_CONV_GEMM=0 MIOPEN_FIND_MODE=1 pytest test_nn.py -v -k "test_conv_cudnn_nhwc" `
2. Example usage 2: Run the following with `PYTORCH_MIOPEN_SUGGEST_NHWC=1` on ROCm4.3.
```
#!/usr/bin/env python3
import torch
model = torch.nn.Conv2d(8, 4, 3).cuda().half()
model = model.to(memory_format=torch.channels_last)
input = torch.randint(1, 10, (2, 8, 4, 4), dtype=torch.float32, requires_grad=True)
input = input.to(device="cuda", memory_format=torch.channels_last, dtype=torch.float16)
# should print True for is_contiguous(channels_last), and strides must match NHWC format
print(input.is_contiguous(memory_format=torch.channels_last), input.shape, input.stride() )
out = model(input)
# should print True for is_contiguous(channels_last), and strides must match NHWC format
print("Contiguous channel last :", out.is_contiguous(memory_format=torch.channels_last), " out shape :", out.shape, "out stride :", out.stride() )
```

With some [new additions](https://github.com/google/breakpad/compare/main...driazati:main) this fork now includes a CMake based build, so we can add breakpad as a proper dependency rather than rely on including it in Docker images as a system library which is error prone (we have a bunch of images) and hard to extend to MacOS / Windows. This also includes some changes to the crash handling code to support MacOS / Windows in a similar way to Linux.
```python
import torch
# On Windows this writes crashes to C:\Users\<user>\AppData\pytorch_crashes
# On MacOS/Linux this writes crashes to /tmp/pytorch_crashes
torch.utils._crash_handler.enable_minidumps()
# Easy way to cause a segfault and trigger the handler

3. Run: `IN_CI=1 python test/run_test.py -i test_cpp_extensions_jit -- -k test_jit_cuda_extension` and notice that it should skip. If it doesn't skip, edit test/.pytorch-disabled-tests.json: modify the platforms list of the first issue (61655) to include whatever platform you are on (macos or linux), and just run `python test/test_cpp_extensions_jit.py -v -k test_jit_cuda_extension --import-disabled-tests` to make sure it skips.
4. Now `export PYTORCH_IGNORE_DISABLED_ISSUES=61655` or `export PYTORCH_IGNORE_DISABLED_ISSUES=34952,61655`.
5. `rm test/.pytorch-*` to clear the cached files.
6. Run the same command as in step 5 and note that it SHOULDN'T skip. It should run.

Summary:
Adds a new `ModuleInfo`-based test to `test_modules.py`.
The test passes `device` and `dtype` to each module during instantiation, ensuring that the kwargs are applied to any newly-created parameters or buffers. Note that the `device` and `dtype` kwargs should only be present when a module creates parameters or buffers; the test uses some mock magic to identify this.

Summary:
This creates `torch.cuda.set_warn_on_synchronization()` function that would warn or error when synchronizing operation is performed. We could wrap it in a context manager for ease of use, but it would be a lie, because it sets global, and not thread-local state. Since it's intended for debugging, maybe that's ok though.
As all `torch.cuda.*` functions, it's going through CPython, not pybind, so the argument is converted to long before being passed to c10 function. I'll make python argument a python enum class, but without pybind it'll still have to go thourgh long conversion.
For a test script
```
import torch
torch.cuda.set_warn_on_synchronization(1)
x=torch.randn(10, device="cuda")
x.nonzero()
y=torch.randn((), device="cuda")
if y:
print("something")

mask = torch.randint(2, (10,), device="cuda", dtype=torch.bool)
val = torch.randn((), device="cuda")
x[mask]=1.

### Remaining Tasks
- [ ] Collate results of benchmarks on two Intel Xeon machines (with & without CUDA, to check if CPU throttling causes issues with GPUs) - make graphs, including Roofline model plots (Intel Advisor can't make them with libgomp, though, but with Intel OpenMP).
### Summary
1. This draft PR produces binaries with with 3 types of ATen kernels - default, AVX2, AVX512 . Using the environment variable `ATEN_AVX512_256=TRUE` also results in 3 types of kernels, but the compiler can use 32 ymm registers for AVX2, instead of the default 16. ATen kernels for `CPU_CAPABILITY_AVX` have been removed.
2. `nansum` is not using AVX512 kernel right now, as it has poorer accuracy for Float16, than does AVX2 or DEFAULT, whose respective accuracies aren't very good either (#59415).
It was more convenient to disable AVX512 dispatch for all dtypes of `nansum` for now.
3. On Windows , ATen Quantized AVX512 kernels are not being used, as quantization tests are flaky. If `--continue-through-failure` is used, then `test_compare_model_outputs_functional_static` fails. But if this test is skipped, `test_compare_model_outputs_conv_static` fails. If both these tests are skipped, then a third one fails. These are hard to debug right now due to not having access to a Windows machine with AVX512 support, so it was more convenient to disable AVX512 dispatch of all ATen Quantized kernels on Windows for now.
4. One test is currently being skipped -
[test_lstm` in `quantization.bc](https://github.com/pytorch/pytorch/issues/59098) - It fails only on Cascade Lake machines, irrespective of the `ATEN_CPU_CAPABILITY` used, because FBGEMM uses `AVX512_VNNI` on machines that support it. The value of `reduce_range` should be used as `False` on such machines.
The list of the changes is at https://gist.github.com/imaginary-person/4b4fda660534f0493bf9573d511a878d.
Credits to ezyang for proposing `AVX512_256` - these use AVX2 intrinsics but benefit from 32 registers, instead of the 16 ymm registers that AVX2 uses.
Credits to limo1996 for the initial proposal, and for optimizing `hsub_pd` & `hadd_pd`, which didn't have direct AVX512 equivalents, and are being used in some kernels. He also refactored `vec/functional.h` to remove duplicated code.
Credits to quickwritereader for helping fix 4 failing complex multiplication & division tests.
### Testing
1. `vec_test_all_types` was modified to test basic AVX512 support, as tests already existed for AVX2.
Only one test had to be modified, as it was hardcoded for AVX2.
2. `pytorch_linux_bionic_py3_8_gcc9_coverage_test1` & `pytorch_linux_bionic_py3_8_gcc9_coverage_test2` are now using `linux.2xlarge` instances, as they support AVX512. They were used for testing AVX512 kernels, as AVX512 kernels are being used by default in both of the CI checks. Windows CI checks had already been using machines with AVX512 support.
### Would the downclocking caused by AVX512 pose an issue?
I think it's important to note that AVX2 causes downclocking as well, and the additional downclocking caused by AVX512 may not hamper performance on some Skylake machines & beyond, because of the double vector-size. I think that [this post with verifiable references is a must-read](https://community.intel.com/t5/Software-Tuning-Performance/Unexpected-power-vs-cores-profile-for-MKL-kernels-on-modern-Xeon/m-p/1133869/highlight/true#M6450). Also, AVX512 would _probably not_ hurt performance on a high-end machine, [but measurements are recommended](https://lemire.me/blog/2018/09/07/avx-512-when-and-how-to-use-these-new-instructions/). In case it does, `ATEN_AVX512_256=TRUE` can be used for building PyTorch, as AVX2 can then use 32 ymm registers instead of the default 16. [FBGEMM uses `AVX512_256` only on Xeon D processors](https://github.com/pytorch/FBGEMM/pull/209), which are said to have poor AVX512 performance.
This [official data](https://www.intel.com/content/dam/www/public/us/en/documents/specification-updates/xeon-scalable-spec-update.pdf) is for the Intel Skylake family, and the first link helps understand its significance. Cascade Lake & Ice Lake SP Xeon processors are said to be even better when it comes to AVX512 performance.
Here is the corresponding data for [Cascade Lake](https://cdrdv2.intel.com/v1/dl/getContent/338848) -
The corresponding data isn't publicly available for Intel Xeon SP 3rd gen (Ice Lake SP), but [Intel mentioned that the 3rd gen has frequency improvements pertaining to AVX512](https://newsroom.intel.com/wp-content/uploads/sites/11/2021/04/3rd-Gen-Intel-Xeon-Scalable-Platform-Press-Presentation-281884.pdf). Ice Lake SP machines also have 48 KB L1D caches, so that's another reason for AVX512 performance to be better on them.
### Is PyTorch always faster with AVX512?
No, but then PyTorch is not always faster with AVX2 either. Please refer to #60202. The benefit from vectorization is apparent with with small tensors that fit in caches or in kernels that are more compute heavy. For instance, AVX512 or AVX2 would yield no benefit for adding two 64 MB tensors, but adding two 1 MB tensors would do well with AVX2, and even more so with AVX512.
It seems that memory-bound computations, such as adding two 64 MB tensors can be slow with vectorization (depending upon the number of threads used), as the effects of downclocking can then be observed.

This makes the breakpad build more explicit in its messaging and hints to cmake where to look for the library (it wasn't able to find it without `PATHS` on CI even though that works locally). This also adds a smoke test that will fail if breakpad isn't present on a CI job where it is expected (e.g. binary builds).

Summary:
This PR will ideally add `ref` argument to `OpInfo` base class. The idea is to add reference checks for all the ops _eligible_. For more discussion, please check https://github.com/pytorch/pytorch/issues/58294
* [x] Migrate (but not removing yet) and modify helper functions from `UnaryUfuncOpInfo` class to `OpInfo` base class.
* [x] Test the reference checks for multiple ops. (also decide a list of different and eligible ops for this)
* [x] Handle possible edge cases (for example: `uint64` isn't implemented in PyTorch but is there in NumPy, and this needs to be handled -- more on this later) -- _Update_: We decided that these reference tests should only test for values and not types.
* [x] Create a sample PR for a single (of all different categories?) on adding reference functions to the eligible ops. -- _Update_: This is being done in this PR only.
* [x] ~Remove reference tests from `test_unary_ufuncs.py` and test to make sure that nothing breaks.~ (*Update*: We won't be touching Unary Ufunc reference tests in this PR)
* [x] Add comments, remove unnecessary prints/comments (added for debugging).
Note: To keep the PR description short, examples of edge cases encountered have been mentioned in the comments below.

`IS_PYTORCH_CI` and `IN_CI` are used randomly, however in some cases IN_CI is not currently set because it only exist in .circleci/scripts/setup_ci_environment.sh. This cleans up the 2 flags and only use IN_CI

Summary:
During development it is common practice to put `type: ignore` comments on lines that are correct, but `mypy` doesn't recognize this. This often stems from the fact, that the used `mypy` version wasn't able to handle the used pattern.
With every new release `mypy` gets better at handling complex code. In addition to fix all the previously accepted but now failing patterns, we should also revisit all `type: ignore` comments to see if they are still needed or not. Fortunately, we don't need to do it manually: by adding `warn_unused_ignores = True` to the configuration, `mypy` will error out in case it encounters an `type: ignore` that is no longer needed.

Do not reorder tests unless they are in IN_CI, this causes local development test ordering indeterministic. most of use branch out from viable strict not head of master.

Summary:
The run-specified-test-cases option would allow us to specify a list of test cases to run by having a CSV with minimally two columns: test_filename and test_case_name.
This PR also adds .json to some files we use for better clarity.
Usage:
`python test/run_test.py --run-specified-test-cases <csv_file>` where the csv file can look like:
```
test_filename,test_case_name,test_total_time,windows_only_failure_sha_count,total_sha_count,windows_failure_count,linux_failure_count,windows_total_count,linux_total_count
