Fixing pytorch/vision#3251 (PR #49410 triggers the torch vision test build failure, on three tests test_faster_rcnn, test_mask_rcnn, test_keypoint_rcnn. )
The offending PR is fine on pytorch UT, because the torchvision and pytorch test has a gap when we merge them - we are using different test API on two sides, therefore causing some discrepancy.
This PR bridge the gap for the above three tests, and disable _jit_pass_onnx_fold_if pass until it gets fixed.
Allow _jit_pass_onnx_fold_if only when dynamic_axes is None.

Summary:
* Support propagating `dim_param` in ONNX by encoding as `ShapeSymbol` in `SymbolicShape` of outputs. If export is called with `dynamic_axes` provided, shape inference will start with these axes set as dynamic.
* Add new test file `test_pytorch_onnx_shape_inference.py`, reusing all test cases from `test_pytorch_onnx_onnxruntime.py`, but focus on validating shape for all nodes in graph. Currently this is not enabled in the CI, since there are still quite some existing issues and corner cases to fix. The test is default to run only at opset 12.
* Bug fixes, such as div, _len, and peephole.cpp passes for PackPadded, and LogSoftmaxCrossEntropy.

Summary:
It is often that the conversion from torch operator to onnx operator requires input rank/dtype/shape to be known. Previously, the conversion depends on tracer to provide these info, leaving a gap in conversion of scripted modules.
We are extending the export with support from onnx shape inference. If enabled, onnx shape inference will be called whenever an onnx node is created. This is the first PR introducing the initial look of the feature. More and more cases will be supported following this PR.
* Added pass to run onnx shape inference on a given node. The node has to have namespace `onnx`.
* Moved helper functions from `export.cpp` to a common place for re-use.
* This feature is currently experimental, and can be turned on through flag `onnx_shape_inference` in internal api `torch.onnx._export`.
* Currently skipping ONNX Sequence ops, If/Loop and ConstantOfShape due to limitations. Support will be added in the future.

Summary:
in `_jit_pass_onnx`, symbolic functions are called for each node for conversion. However, there are nodes that cannot be converted without additional context. For example, the number of outputs from split (and whether it is static or dynamic) is unknown until the point where it is unpacked by listUnpack node. This pass does a preprocess, and prepares the nodes such that enough context can be received by the symbolic function.
* After preprocessing, `_jit_pass_onnx` should have enough context to produce valid ONNX nodes, instead of half baked nodes that replies on fixes from later postpasses.
* `_jit_pass_onnx_peephole` should be a pass that does ONNX specific optimizations instead of ONNX specific fixes.
* Producing more valid ONNX nodes in `_jit_pass_onnx` enables better utilization of the ONNX shape inference https://github.com/pytorch/pytorch/issues/40628.

Summary:
Add pass that fuses Conv and Batchnormalization nodes into one node Conv.
This pass is only applied in inference mode (training is None or TrainingMode.Eval).
Since this pass needs access to param_dict it is written outside peephole file where these kind of passes (fusing multiple nodes into one) is usually placed.
This PR also adds wrapper skipIfNoEmbed to skip debug_embed_params test:
Pass that fuses Conv and Batchnorm changes the params of resnet model and parameters of onnx and pytorch model won't match. Since parameters are not matching, debug_embed_params test for test_resnet will fail and that is expected, therefore debug_embed_params test for test_resnet should be skipped.

Summary:
With https://github.com/pytorch/pytorch/pull/35562, we are running peephole optimization on inlining to reduce the number of nodes that are copied.
The tracer encodes the sizes in the graph like:
```
graph(%0 : Double(7)):
%1 : Function = prim::Constant[name="tensor_size"]()
%2 : Tensor = prim::CallFunction(%1, %0)
return (%2)
```
however people would like to reuse the graph with different shapes so running size invalidations would invalidate that. long term it might be better for the tracer to not include shape information but there are downstream users of that.
Separates out FuseAddMM from peephole so that now there is a single `disable_size_optimizations` parameter, and onnx explicitly invokes fuseaddmm.

While ONNX does not currently directly support the Dim operation on a
tensor, we can provide the same functionality with two ONNX operations.
This allows us to support Dim for all opsets. It may be adventageous to

efficient code.
While testing dim op found that there is an issue with empty blocks
withing if statements. Modified graph generation to prevent generation
of empty if blocks.

ind2 = torch.tensor([1, 1])
x[1:3, ind1, ind2, ..., 3] = data
```
Limitations:
Tensor indices must be consecutive, and 1-d tensors.

Summary:
The PyTorch exporter does not add any name to the ONNX operators in the exported graph. A common request is to add names to op nodes by default. This helps the readability of the graph in visualization tools such a Netron, or when the ONNX graph is printed as a string. Also, it helps with the debuggability of the ONNX graph.
Therefore this PR adds name to operators in the exporters. The names follow a simple format, <op_type>_<index>. Expect files for tests in `test/onnx/test_operators.py` have been updated.

This should resolve https://github.com/pytorch/pytorch/issues/29008. This flag has two effects on the tracer.
- Remove the underscroll for inplace operators. E.g.: index_put_ ==> index_put. This is handled in utils.py separately as well.
- Add out as input for backward computation.

This PR adds preliminary support required to be able to run quantized pytorch models on a C2 backend.
For quantized ops we use a custom domain name 'caffe2' to register the ops if they are in the "quantized" namespace.
The change also adds JIT pass to unpack the quantized weights and insert the unpacked values into the graph.
The actual tensor values are looked up from the params dict.

Summary:
Currently, `keep_initializers_as_input` argument in `torch.onnx.export` API can be used to choose whether to export an ONNX model with IR v3 or v4 semantics. Currently, the implementation does not check for which opset is being used for export. This is an issue because ONNX IR v4 is valid only for opset 9 and above (as listed [here](https://github.com/onnx/onnx/releases/tag/v1.4.0)), and opset 8 or lower export with `keep_initializers_as_input=False` will create a illegal ONNX graph.
This change fixes this by introducing a check on opset version when deciding whether to export ONNX IR v3 or v4.

Summary:
Currently ONNX constant folding (`do_constant_folding=True` arg in `torch.onnx.export` API) supports only opset 9 and 10 of ONNX. Opset 11 support was recently introduced in the ONNX exporter. For opset 11, it is currently a no-op. This change enables ONNX constant folding for opset 11. Specifically there are three main changes:
1) Turn on constant folding ONNX pass for opset 11.
2) Enable constant folding tests in `test/onnx/test_utility_funs.py` and `test/onnx/test_pytorch_onnx_onnxruntime.py` for opset 11.

There is no reason to have it in a general API of Module/Method - it's
just another graph pass. It was there because some time ago modules were
not first class and all graphs were lowered. After that changed, this
API was added for easier transition, but now we don't need it anymore.

Summary:
We currently support exporting traced interpolate ops to ONNX.
Scripting interpolate op invokes aten::__interpolate in the Torch IR (instead of aten::upsample_[mode][dim]d), which we do not support yet.
This PR implements the ONNX symbolic for __interpolate() to support exporting interpolate in scripting scenarios.

Summary:
ONNX does not support dictionaries for inputs and output. The reason is that the arg flattening and unflattening does not handle Dictionary types.
This PR adds flattening/unflattening support for dictionaries and strings.
However this feature should be handled with caution for input dictionaries; and users need to verify their dict inputs carefully, and keep in mind that dynamic lookups are not available.
This PR will allow exporting cases where models have dictionnary outputs (detection and segmentation models in torchvision), and where dictionary inputs are used for model configurations (MultiScaleRoiAlign in torchvision).

someone may use torch._export directly. Here we change the onnx_export_type's default value to None,
and if it's pytorch onnx caffe2 bundle, we set it to ONNX_ATEN_FALLBACK, otherwise, it's ONNX.

Summary:
This is a follow-up PR for https://github.com/pytorch/pytorch/pull/23284. In that PR we had removed changing the default behavior for `keep_initializers_as_input` argument to the export API. With this PR we are enabling that change in that if `keep_initializers_as_input` is not specified then value/behavior for this argument is chosen automatically depending on whether the export type is ONNX or not.
This was part of the earlier PR was removed for further review. The test points have also been updated.
This change may fail some internal tests which may require explicitly setting `keep_initializers_as_input=True` to preserve old behavior.

The way it is implemented currently is bad because while we're inlining
to a graph G, we are also mutating all the graphs that are being
inlined. The problem is that the graphs we're inlining are usually the
original graphs of functions, so we're silently changing them behind the
scenes, and we don't have a way to recover 'unoptimized' graphs
afterwards.

Before, we inlined as part of the initial IR generation process, which
has a few disadvantages:
1. It loses information about what nodes came from which function/method
calls. Other parties who want to implement transformations on the
function/module level don't have a reliable way of doing so.
2. It duplicates a ton of code if we are inlining the same
function/method a tons of times.
After this PR: inline is deferred to the optimization stage, so
optimizations that rely on inlining will still work. But things get
serialized with the function/method calls in.

Summary:
Starting ONNX IR version 4, the initializers in the ONNX graph do not have to be inputs of the graphs. This constraint, which existed in IR version 3 and earlier, was relaxed in IR version 4. This PR provides an API level argument to allow ONNX export with the relaxed constraint of IR version 4, i.e. provides the option to not include initializers as inputs. This allows backends/runtimes to do certain optimizations, such as constant folding, better.
*Edit*: After discussion with houseroad we have the following behavior. For any OperatorExportType, except OperatorExportTypes.ONNX, the current status of export is maintained in this PR by default. However, the user can override it by setting the `keep_initializers_as_inputs` argument to the export API. But when exporting to ONNX, i.e. OperatorExportType is OperatorExportTypes.ONNX, the current status is changed in that by default the initializers are NOT part of the input. Again, the default can be overridden by setting the `keep_initializers_as_inputs` argument.
