Summary:
This refactors pybind_utils so we can have all our type-inferring stuff in
1 place (e.g. for #21379)
There is some follow up work to make the error messages better, but I think that's fine to save for another PR.

Summary:
Resubmit #20698 which got messed up.
Idea is that when PyTorch is used in a custom build environment (e.g. Facebook), it's useful to track usage of various APIs centrally. This PR introduces a simple very lightweight mechanism to do so - only first invocation of a trigger point would be logged. This is significantly more lightweight than #18235 and thus we can allow to put logging in e.g. TensorImpl.
Also adds an initial list of trigger points. Trigger points are added in such a way that no static initialization triggers them, i.e. just linking with libtorch.so will not cause any logging. Further suggestions of what to log are welcomed.

Summary:
The PR clang-formats everything in `torch/csrc/jit/` and adds it to the pre-commit hook.
Here is a list of non-mechanical changes:
- I went over each file and fixed up whenever I could tell that clang-format was clobbering comment formatting.
- Made the macros in register_prim_ops a little more clang-format friendly by omitting trailing commas
- Refactored autodiff.cpp to use a helper class with explicit state rather than a bunch of capturing lambdas
- Small improvements to the precommit hook clang-format

Summary:
This PR changes Method (just Method not all graphs) to always have a single
return argument.
This is part 1 in a set of changes that will enable us to have better handling if early return statements.
The simplification that this change provides greatly reduces the work for the next step.
This change makes it so that Method and Python handle multiple returns in the same way:
* 0 - None
* 1 - <single value>
* many - Tuple[...]
The result is that a lot of special-case handling in compiler.cpp and its
bindings can be removed. It also fixes several bugs in return handling,
including one where return values were not always checked against their
attributed values.
Notes:
* inferTypeFrom is renamed to be more accurate and discourage use.
* This has uncovered some bugs in other components, which are noted in
the diff.

Summary:
This PR adds the final set of clang-tidy checks we should add for our codebase: a last set of performance-related checks. Most fixes here are around changing `auto` to `const auto&` in a few places where unnecessary copies were made, and adding `reserve()` calls before loops doing repeated `push_back()`. Also a few cases of calling `std::string::find` with a single-character string literal instead of a single char, which uses a less efficient string search algorithm meant for searching larger substrings.

Summary:
This PR adds a `try_outplace` option to the tracer. When `try_outplace` is true, the tracer will attempt to out-of-place ops (similar to how things are done today). When it's false, the correct in-place op is emitted.
I made `try_outplace` false by default, but flipped it to true for ONNX export utils. zdevito jamesr66a, anywhere else I should preserve the existing behavior?

Summary:
export - print a method with python_print
import - import a method with import_method
We want to ensure:
export(g) == export(import(export(g)))
That is after after exporting/importing once, the graph will stay exactly
the same. This is less strict that g == import(export(g)) which would
require us to maintain a lot more information about the structure of the
IR and about the names of debug symbols.
This PR addresses this with the following fixes:
* print out double-precision numbers with high enough precision such
that they always parse in the same way
* when creating loop-carried dependencies, sort them
by variable name, ensuring a consistent order
* parse nan correctly
* DCE: remove unused outputs of if statements, and loop-carried dependencies
in loops that are dead both after the loop and inside the body of the
loop.
* Do not set uniqueName for variables whose names are _[0-9]+, these
are probably rare in user code, and we need a way to communicate
that we do not care about a variable name when re-parsing the graph.
Otherwise temporary variable names will jitter around.
* Expand the definition of a constant in printing code to None,
and family.
* Allow re-treeing to work as long as the only thing in its way is a
constant node. These do not have side effects but are sometimes
inserted in a different order when tracing compared to how we print them.
* Print all constant nodes out first in the order in which they are used_val
(or, if they are inlined, ensure they get assigned CONSTANT.cX number
in a consistent order). Cleanup tuples (this is done in the compiler,
but not in the tracer, leading to some tuple indexing jitter if not
done).
* use strtod_l, not std::stod which can throw exceptions
Other:
* Add REL_WITH_DEB_INFO to setup.py. It already existed for the
cmake files. Threading it into setup.py allows us to turn on
debug symbols with optimization everywhere.
* enable round trip testing for all generated graphs. This only adds
~6 seconds to total build time but tests printing for every graph.

Summary:
There are still a few work to be done:
- Move logging and unify AT_WARN with LOG(ERROR).
- A few header files are still being plumbed through, need cleaning.
- caffe2::EnforceNotMet aliasing is not done yet.
- need to unify the macros. See c10/util/Exception.h
This is mainly a codemod and not causing functional changes. If you find your job failing and trace back to this diff, usually it can be fixed by the following approaches:
(1) add //caffe2/c10:c10 to your dependency (or transitive dependency).
(2) change objects such as at::Error, at::Optional to the c10 namespace.
(3) change functions to the c10 namespace. Especially, caffe2::MakeString is not overridden by the unified c10::str function. Nothing else changes.
Please kindly consider not reverting this diff - it involves multiple rounds of rebasing and the fix is usually simple. Contact jiayq@ or AI Platform Dev for details.

Summary:
This PR adds tracing infrastructure for custom operators. It also simplifies the tracer overall, and changes the codegen to do more metaprogramming there instead of via C++ (which was necessary for the custom op tracing).
To give an example of the tracer/metaprogramming change, what used to look like this in `VariableType.cpp`:
```
jit::tracer::PreTraceInfo trace_info;
if (jit::tracer::isTracing()) {
trace_info = jit::tracer::preRecordTrace(jit::aten::index_select, "self", self, "dim", dim, "index", index);
}
```
is now simply the inlined version of `preRecordTrace`, minus C++ metaprogramming:
```
torch::jit::Node* node = nullptr;
if (jit::tracer::isTracing()) {
auto& graph = jit::tracer::getTracingState()->graph;
node = graph->create(jit::aten::index_select_out, /*outputs=*/0);
jit::tracer::recordSourceLocation(node);
jit::tracer::addInputs(node, "result", result);
jit::tracer::addInputs(node, "self", self);
jit::tracer::addInputs(node, "dim", dim);
jit::tracer::addInputs(node, "index", index);
graph->appendNode(node);
}
```

Summary:
More clang tidy cleanups in `torch/csrc`. This time:
1. `hicpp-use-equals-default` recommends `= default` instead of `{}` for constructors/destructors. This is better practice because it expresses the intent better (https://stackoverflow.com/questions/6502828/what-does-default-mean-after-a-class-function-declaration)
2. `readability-inconsistent-declaration-parameter-name` enforces that parameter names in the declaration match parameter names in the definition. This is just generally useful and can prevent confusion and bugs.
Also updated my script a little bit.

Summary:
Based on top of #9763 (first 3 commits belong to that PR). The first commits from this PR are "Stop using attributes ..."
I tried to separate the changes into fairly meaningful commits. I can't split them up into smaller PRs, because everything starts working and all tests pass only after the whole sequence, but hopefully this will make reviewing somewhat easier.
Known issues/regressions/future tasks:
- `aten::lerp` and `aten::clamp` are no longer fusable
- `CreateAutodiffSubgraphs` needs a rewrite
- It is much more strict now, and will miss a lot of opportunities, especially when viewing ops are involved. Our previous approach was "ignore the assumption on shape availability in gradient formulas to determine differentiability, and hope that shape prop will be robust enough to actually deliver them before we differentiate", which obviously doesn't scale well to more complex cases. We should either work on reducing the size dependency of grad formulas (feasible e.g. for `view`/`reshape`, unfeasible for `squeeze`/`unsqueeze`), or make `CreateAutodiffSubgraphs` integrate some kind of "I could integrate this node into an AD subgraph, but will I be able to infer the shape of its input" reasoning (kind of like a limited shape prop, that doesn't infer anything, and only tells if it *could* infer something).
- It sometimes creates constant-only (or constants + one node) graphs, which is useless
- Broken `aten::add` in auto-batching, because it gained a non-tensor input. I changed the test for pointwise operations to use `aten::mul` instead, but I needed to disable the LSTM cell test. I'm not sure how scalar constants should be implemented in this case, because I don't fully understand our format. cc: ChunliF
- Graph import does some hacks to recover type of constants. This code should be removed once we'll gain the ability to export the IR along with value types.
- There's still a fair amount of dead code that can be removed. I didn't want to make this diff any bigger, and removing it is an easy task.
- Graph fuser could be improved to use signature matching (possibly using `OperatorSet`) instead of basing on node kinds.
- Manual constant propagation for the `ListConstruct` node in `torch/onnx/utils.py` should be replaced with a proper constant propagation pass (or we should ensure that the one we have handles at least this case before we remove this code).

Summary:
I got some tensor->variable conversion exceptions from `torch/csrc/autograd/variable.h`, which used the `TORCH_ASSERTM` macros instead of `AT_CHECK`, so they didn't have backtraces. This was such a substantial loss for debugability that I decided to update the whole codebase to use the backtrace-enabled ATen macros instead of `TORCH_ASSERT` and `JIT_ASSERT`, the latter having been an alias of the former.

The long-term fix is to remove the handling-creating pathways and
remove all the modes from PythonOp making it into an op that simply
calls a PyObject. Right now ONNX expects PythonOp to hold a
nn.Function, not a generic callable, so completely removing the legacy
pathway will also require changes to how ONNX symbolics are found.
* Switch JIT passes to take a graph rather than TracingState
* Add pybind11 binding for ONNX pass from graph
* Fix canonicalize pass
* address comment
* Switch ToONNX to explicitly return new graph
* optimize_graph instead of optimize_trace
Allows you to export an ONNX model as:
Protobuf file (this is what we have now)
Uncompressed zip archive
Compressed zip archive
Directory
* Experimental support for different ONNX export types
* Remove a copy
* Add comment
* Add test cases
* lint
* fix bug
* address comments
ExportProxy was a mechanism to reuse the code that supported exporting
autograd Functions to support overriding arbitrary python
functions. However, it had some serious downsides
- only works on some functions (all args must be Variable)
- complicated
- bad error messages in some cases
Instead, just expose enough functionality to python to perform the
necessary logic explicitly.
