This prepares the PR where we implement sets in terms of dicts.
To do so, rather than storing internally a dictionary that maps literals
to VariableTrackers, it stores (pretty much) a dictionary from VTs to VTs.
To do so, keys are wrapped in an opaque internal class _Hashable.
The Hashable class is opaque on purpose so that it fails hard if
if it inadvertently leaks back into user code.
We also found and fixed a number of latent bugs and inconsistencies
in the way dynamo checked what can be a dict key. More generally, we
make much clearer what are the things that need to be modified to add
a new supported key type to Dicts.

After this refactor:
* ```TorchVariable``` definition and all references are removed.
* All ```is_allowed``` references except one are removed.
- The only left one is in ```torch/_dynamo/decorators:_disallow_in_graph_helper```. It was called when users put ```disallow_in_graph``` decorator on a function. Since we use the lists in ```trace_rules``` to decide the function's trace rule, so the decorator would only be used as customer function rather than torch functions. I'll defer this to a separate decorator refactor PR.

Recent 2 triton PRs (https://github.com/openai/triton/pull/2701, https://github.com/openai/triton/pull/2756) change the interface for triton.compile, this PR added the necessary change on inductor side to work with both old and new compile API.
Also there is some simplification between compilation call in subprocess and the one in main process
- previously we pass warm_cache_only=True if the compilation happens in subprocess. But triton never use that argument in the currently used pin. So I removed that
- previously we only pass compute_capability if compilation happens in subprocess. The PR change that to always passing compute_capability to triton.compile no matter if the compilation happens in main or sub process.
Updated:
There are more interface change from triton side. E.g.
- tl.math.{min, max} now requires a propagate_nan argument
- JITFunction.run now requires a warmup argument. This affect the benchmarking phase of matmul max-autotune; on the other hand, JITFunction.run forbids stream argument now. Simply removing passing this in when benchmarking matmul triton kernel will work for both old and new version of triton.
- triton Autotuner change attribute name from 'warmup' to 'num_warmup' and from 'rep' to 'num_rep'. This cause dynamo failed to handle triton Autotuner object since dynamo TritonKernelVariable makes assumption about attribute names. It's used in some test cases that a model call triton Autotuner directly.

Make ```SkipFilesVariable``` only handle function type, and route skipped classes to ```UserDefinedClassVariable```. The reasons behind this are:
* We'd like to remove ```is_allowed```, so the allowed/disallowed torch classes should have a proper place to handle. We can put them in either ```SkipFilesVariable``` and ```UserDefinedClassVariable``` under the current architecture, but it's confusing to have two places do one thing.
- Going forward, let's make ```SkipFilesVariable``` only handle functions, and probably I'll rename it to ```SkippedFunctionVariable``` in the following PRs.
- Let's do dispatch by value's type, all torch classes stuff would go to ```UserDefinedClassVariable``` in the next PR.
* We'd merge in_graph/skip/inline trace decision into the same API ```trace_rule.lookup```, so probably we have to limit the input to only function for better organizing ```VariableBuilder._wrap``` logics.
- Next step, I'll merge ```skipfiles.check``` into ```trace_rules.lookup```, and do the skipfile check before wrapping them into correct variable tracker.
- Though the ```TorchCtxManagerClassVariable``` is decided by ```trace_rules.lookup```, I'll refactor it out in the following PRs.

Motivation: it would be nice to be able to test using the metrics in log_compilation_event; currently dumps logs (or logs to a database in fbcode) - these are hard to use in unit tests.
This change:
* always record the information in torch._dynamo.utils.record_compilation_metrics; here, log into a limited-size deque to prevent the list of metrics from getting too long
* if config.log_compilation_metrics, then call back into the original log_compilation_event function

1. Removes calls to `replace_all` and `clone` and makes VTs mutable.
2. Properly handles Tuple Iterator mutation. Previously TupleIterator variables would only be properly reconstructed if they were advanced at least once in a frame. On calls to `next`, the source information would be lost (due to constructing a new iterator without using builder), which would ensure that during codegen the variable would be reconstructed from scratch. Now that VTs are mutated, the source is never lost, so we need to properly track mutation and handle it by replaying calls to `next` at the end of the modified bytecode.
3. Added test for checking iadd side effects, this was missing in our unit test coverage.
4. Fixed two incorrect sources, DelayGraphBreakVariable, and UserMethodVariable both relied on setting the source to AttrSource(parent, name) at the callsite of `var_getattr`.
5. Fixed a bug in inplace adding for lists, it would set the resulting VariableTracker's source to `None` which would utilize a different reconstruct path in codegen. Now this is handled explicitly by reconstructing vars when allow_cache=`False`, so that during side effect replay, the mutated var is correctly updated.
In subsequent PRs:
* Refactoring side effect tracking to be significantly simpler (I think we only need an `is_modified` flag)
* Refactor `next_variables` iterator to match the signature of `next`
* Remove all references to `options` in the code
* Refactor VTs representing mutable collections to implement their own mutation update handling
* Remove clone and/or make it specific to lists for creating slices
* Add mutation tracking/replay for sets
* Add mutation tracking/replay for iter.py
* Removing setting source in builder (it's set at the top level after a var is returned)

Summary:
The primary problem we are setting out to solve here is fake tensor freshness. Before this PR, fake tensors after dynamo represented fake tensors *at the end* of trace, so subsequent retraces like aot_autograd would start off with fake tensors in the wrong (end result) state, rather than their expected fresh state. The solution here is to start a fresh fake mode, and re-fakify the tensors. The nuance comes from ensuring that symbols are uniformly created for the symbolic sizes and strides of the tensor.
This PR is the result of *a lot* of back and forth with ezyang and eellison. Initially, the first pass at this was not super different from what we have in the PR - the broad strokes were the same:
1) We cache source->symbol in shape_env
2) We pass policy objects around, stored at dynamo fakificaiton time, and reused for later fakification
3) We create a new fake mode for backends
(from https://github.com/pytorch/pytorch/pull/113605/files)
This is ugly, and has some layering violations. We detoured our decision making through a few other alternatives. Immutable/mutable fake tensor mode was the most interesting alternative, https://github.com/pytorch/pytorch/pull/113653, and was struck down on concerns of complexity in fake mode combined with it not covering all edge cases. We also detoured on what to do about tensor memoization returning back potentially different tensors than requested, and if that was an anti pattern (it is) we want to hack in with the symbol cache (we don't).
We went back to the drawing board here, but with a few concessions:
1) the cache for source->symbol must live outside of shape_env, for both lifecycle, and layering reasons
2) A good amount of work needs to be done to pipe policy around fake_mode and meta_utils correctly, to cover all the cases (ezyang did this)

Skipping importing some packages for now to make this change more
tractable.
For some reason, lintrunner on CI raises errors in all imported `.pyi` files,
even though it doesn't on my local machine. The errors are all from missing
generic types, as the MYPYINDUCTOR config has `disallow_any_generics`
set. I have thus added `disable-error-code` comments to the relevant files,
though I fixed a few that were easy enough.

Followup to https://github.com/pytorch/pytorch/pull/110325 - re-add the `report_all_guard_failures config` as a logging artifact `recompiles_verbose` with the following changes:
- evaluating the check must be wrapped with exception handling because subsequent code parts following the first failure may result in errors if evaluated (e.g. if a guard checks first for size, then tries to index - a guard failure due to insufficient size would result in an index error for the latter check).
- Adding a test for this case

```python
import torch
def fn(x):
return torch.rand(x[-1], len(x))
opt_fn = torch.compile(fn)
opt_fn([4, 5, 6])
opt_fn([7, 8])
opt_fn([9])

This prepares the PR where we implement sets in terms of dicts.
To do so, rather than storing internally a dictionary that maps literals
to VariableTrackers, it stores (pretty much) a dictionary from VTs to VTs.
To do so, keys are wrapped in an opaque internal class `_Hashable`.
The Hashable class is opaque on purpose so that it fails hard if
if it inadvertently leaks back into user code.
We also found and fixed a number of latent bugs and inconsistencies
in the way dynamo checked what can be a dict key. More generally, we
make much clearer what are the things that need to be modified to add
a new supported key type to Dicts.

Notes:
* `debug_insert_nops` in testing.py was passing `None` to the compiler_fn
parameter of `OutputGraph`, hence the modifications there.
* I added `disable-error-code="method-assign"` to debug_utils.py as it
does several such assignments. I guess mypy doesn't like it because it
makes code near-impossible to safely typecheck.

Attempt number 2 at https://github.com/pytorch/pytorch/issues/108950.
Improves debugging for guard failures/recompilations by:
- only running guard fail reason generation during recompilation, instead of when a guard fails during dynamo cache lookup (so generating guard failure reasons is not on the critical path)
- ~~always reporting all guard failures~~ Reports the first-failing guard failure for each cache entry.
We don't expect a performance hit since the guard fail reasons are only generated at recompile time rather than runtime. Perf benchmark to check this (https://hud.pytorch.org/benchmark/torchbench/inductor_with_cudagraphs?startTime=Fri,%2027%20Oct%202023%2017:42:43%20GMT&stopTime=Fri,%2003%20Nov%202023%2017:42:43%20GMT&granularity=hour&mode=training&dtype=amp&lBranch=gh/williamwen42/62/head&lCommit=f4724f5ffc6d17ceae513a42fc18627be7b85482&rBranch=main&rCommit=29f3d392bf230072e3bffae37b078e770cae1956). We may also need to verify this on benchmarks where guard fails are common.

```python
import torch
def generate_data(b):

torch.randn(b, 3, 32, 32).to(torch.float32).cuda(),

Summary:
See internal diff for more changes. Whenever we encounter a non-compliant op,
we add it to a set on the OutputGraph. When a compilation event happens, we log
the contents of this set.
I'm planning on flipping the `only_allow_pt2_compliant_ops` config from False
to True after the logging determines that existing models do not use
non-compliant ops.
Test Plan: - Tested the logging internally locally

Previously, under config.only_allow_pt2_compliant_ops, Dynamo graph
breaks when it see an OpOverloadPacket where any overloads are not
PT2 compliant. This is potentially brittle: if someone (unlikely) adds
a new overload for a custom operator, then this would cause a
previously non-graph-breaking call to the OpOverloadPacket to graph break.
In this PR:
- When Dynamo is about to write a call to an operator to the FX graph,
we check if it is PT2 compliant.
- For OpOverload, we check to see if the tag is on it
- For OpOverloadPacket, we do overload resolution and check to see if
the tag is on the OpOverload that it resolves to.
Test Plan:
- new tests, existing tests

Major change in this PR is to make torch context manager class a separate ```TorchCtxManagerClassVariable```, since we have dynamo implementation for these ctx managers.
I was thinking to wrap them as ```UserDefinedClassVariable``` and do dispatch at ```USCVariable.call_function```, but it seems almost the same amount of work and this way is more clear.
This is on the way of moving ```TorchVariable``` to ```TorchFunctionVariable``` which will only handle the functions who would be allowed in graph (e.g, ```torch.sin```) and constant folded (e.g, ```torch.is_floating_point```). All other torch functions would be go through skip/inline rules, and would be wrapped as ```UserFunctionVariable``` (for inlined) and ```SkipFilesVariable``` (for skipped).
The next steps:
* Wrap torch modules, classes, objects as regular ```PythonModuleVariable```, ```UserDefinedClassVariable``` and ```UserDefinedObjectVariable```.
* Generate the allow in graph torch functions list and wrap them as ```TorchFunctionVariable```.
* Finally merge ```skipfiles.check``` and ```is_allowed``` into one function ```allow_skip.check(fn)``` which would return a Enum of allow, skip and inline.

Triggers `__torch_function__` tracing on attribute/method/property access matching the eager behavior for non-overridden attributes/methods/properties that are present on `torch.Tensor`.
Some caveats:
1. for methods there doesn't seem to be a way to check if the original implementation of a method is overridden via monkey patching or not. For example:
```
class LocalSubclass(torch.Tensor):
@classmethod
def __torch_function__(cls, func, types, args=(), kwargs=None):
if kwargs is None:
kwargs = {}
return super().__torch_function__(func, types, args, kwargs)
x = torch.ones(2, 2).as_subclass(LocalSubclass)
> x.sigmoid
<built-in method sigmoid of LocalSubclass object at 0x7f8d305bb5e0>
```
There isn't a way to verify that this built-in method is equivalent to the base `torch.Tensor` implementation as each instance will have a different built-in method object that can't be traced back to the original `torch.Tensor` impl. You can check that the class itself has the original implementation via
```
> inspect.getattr_static(LocalSubclass, "sigmoid")
<method 'sigmoid' of 'torch._C.TensorBase' objects>
```
But we can't detect if the user dynamically patches an object with a built-in method called sigmoid which does something completely different.
2. If a user overrides a method but calls the original implementation we will still graph break. This will require modifying `SuperVariable` (and any other way to get the original impl) to handle tensor subclasses.

Did some easy fixes from enabling TRY200. Most of these seem like oversights instead of intentional. The proper way to silence intentional errors is with `from None` to note that you thought about whether it should contain the cause and decided against it.

We want to get to a point where most UserErrors link to exportdb examples. This PR makes passing case names non-optional to make this intent clearer and encourage developers who raise UserErrors to make or point to examples that make fixing such errors more obvious for users.
In addition, sometimes there are multiple examples that are relevant to an error. Thus this PR also enables passing multiple case names.

Ideally all `_dynamo.exc.UserError`s should have "case names", i.e., link to examples in `exportdb`.
This PR adds case names to several instances of `_dynamo.exc.UserError`. In particular, looking at coverage based on `UserErrorType`:
* `DYNAMIC_CONTROL_FLOW`, `ANTI_PATTERN`, and `STANDARD_LIBRARY` are fully covered.
* `CONSTRAINT_VIOLATION` and `DYNAMIC_DIM` have no coverage. We don't seem to have any dedicated examples of specifying dynamic shapes in `exportdb` (although they are used in some other examples without explanation, to avoid some specialization that would make such examples moot).
* `INVALID_INPUT` is only partly covered. Frankly this is tedious to cover via examples.

This PR introduces binary search for finding smaller validation errors, when they occur.
We do that by bisecting the sequence of `torch._assert` FX nodes recorded as the source
expression of the translation validator (TV) by `ShapeEnv.evaluate_expr` calls. Then, we
raise the error caused by the earliest node.
In summary, the changes are:
- Call `bisect` on `ValidationError` @ _torch/_dynamo/convert_frame.py_
- Implement the binary search @ _torch/fx/experimental/symbolic_shapes.py_
Edit: moved `ShapeEnv` replay-recording to #107989

Fixes#106893
There are two main changes:
- Before this PR, the function returned by once_differentiable was
included in skipfiles (because its .co_code is
torch/autograd/function.py). This PR adds a mechanism to tell Dynamo
to inline a function, no matter if it is included in skipfiles.
- A bugfix: when we are introspecting the backward, we need to turn the
grad mode off. This is to accurately model the eager-mode semantics:
In eager-mode PyTorch, if second-order gradients were not requested, then
the grad mode is off. torch.compile does not work with higher-order
gradients and just assumes we do first-order gradients, so this is OK.
Test Plan:
- new test

Fixes inference accuracy for `doctr_reco_predictor` and `pyhpc_turbulent_kinetic_energy`.
For the `same(float, float)` comparison we weren't going through the more rigorous tensor comparison path which takes into account the fp64 base results.
Also return True when fp64 base result are not well formed (nan).
I debugged these models and the source of divergence were innocuous:
`doctr_reco_predictor` - can be fixed by turning off layout optimization, decomp for batch norm
`pyhpc_turbulent_kinetic_energy` - divergence caused because fused kernel keeps precision in fp32 instead of casting back and forth from/to fp32/bf16. Fused kernel is better precision, anyway.

There is already some support for plumbing `__torch_dispatch__` tensor subclasses through dynamo, but this PR beefs it up a bit and adds a test. In particular:
(1) Fakeifying tensor subclasses didn't properly set autograd metadata (requires_grad, is_leaf) on the newly fakeified wrapper subclass. I don't actually have a test for this in this PR, but it's tested pretty heavily later in my aot autograd tests
(2) Fakeifying tensor subclasses didn't properly track source information for dynamic shapes on the inner tensors. I added a new `WrapperSubclassFieldSource` subclass, that represents a source coming from a tensor field on a wrapper subclass, which I use in the fakeifying logic, and again in symbolic_shapes.py to generate proper guards.
(3) `_make_wrapper_subclass()` marginally updated this code to work better with dynamic shapes. One thing that's a bit weird about `_make_wrapper_subclass`: it has two overloads, and the first explicitly does not support dynamic shapes (and the second.. does not support kwargs). I think that later we probably want to consolidate / at least make the first overload work with dynamic shapes, but I didn't want to handle that in this PR (so these smaller changes seemed like a strict improvement).

This adds some utilities for conveniently working with fast combined CapturedTraceback from Python. The main goal of these utilities is to make it easier for people to use CapturedTraceback as a drop-in replacement for `traceback.extract_stack`, which is 20x slower than CapturedTraceback.
I port symbolic shapes to use the new CapturedTraceback code, to validate that the APIs work and are useful.

ghstack dependencies: #107438
Adds API to mark tensor as a static input -
To make this trigger recompiles properly, I'll need to update tensor match checks to also check for this new attribute
Additional concern is memory - the tensors will be kept alive, but this is the current behavior for nn modules and parameters.

First commit is the contents of https://github.com/Quansight-Labs/numpy_pytorch_interop/
We have already been using this in core for the last few months as a external dependency. This PR pulls all these into core.
In the next commits, I do a number of things in this order
- Fix a few small issues
- Make the tests that this PR adds pass
- Bend backwards until lintrunner passes
- Remove the optional dependency on `torch_np` and simply rely on the upstreamed code
- Fix a number dynamo tests that were passing before (they were not tasting anything I think) and are not passing now.
Missing from this PR (but not blocking):
- Have a flag that deactivates tracing NumPy functions and simply breaks. There used to be one but after the merge stopped working and I removed it. @lezcano to investigate.
- https://github.com/pytorch/pytorch/pull/106431#issuecomment-1667079543. @voznesenskym to submit a fix after we merge.
All the tests in `tests/torch_np` take about 75s to run.
This was a work by @ev-br, @rgommers @honno and I. I did not create this PR via ghstack (which would have been convenient) as this is a collaboration, and ghstack doesn't allow for shared contributions.

This PR adds a new configuration that enables shapes of torch.nn.Parameter to be treated as dynamic in order to avoid extensive recompilation when Paramters are used instead of Tensor.
