1. right now we double increment the profile counter. The PR avoid that so we don't end up with profile_0, profile_2, profile_4 ...
2. log the latency to run the passed in function with profiling on so we can easily skip those _compile call which returns quickly.

Fix: https://github.com/pytorch/pytorch/issues/119779 by properly graph breaking a proper fix is to handle quantized tensors for full complete solution.
if when generating a fake tensor, UnsupportedFakeTensorException is thrown, then its handled and converted into a
Unimplemented in inside wrap_fake_exception which is then translated to a graph break.
However run_node used to convert UnsupportedFakeTensorException into a runtime error, creating runtime
errors instead of graph breaks whenever generating a fake tensor for a quantized tensor fails.

partially address https://github.com/pytorch/pytorch/issues/118785
This diff fixes three things:
1. add get_function to FunctoolsPartialVariable note that it will be available only if all args constant otherwise,
it would throw unimplemented in the call to asPythonConstant.
2. NamedTupleVariable takes args dispatched not as list ex: NamedTuple(a, b, c) vs NamedTuple([a, b, c]),
hence fix that by specializing asProxy.
3. A call to create_arg from within create_proxy, changes a python NamedTuple to a function call node without
associating an example value! Updated get_fake_values_from_nodes to handle such case.

Finally we have this PR to merge allow_in_graph/inline/skip trace rules into ```trace_rules.lookup_inner```, where we can define and lookup trace rules at both function level and file level. Going forward, this is the central place that we define and consulte Dynamo trace rule for any function.
* ```trace_rules.looup``` is the API can return allow_in_graph, inline or skip.
* ```skipfiles.check``` is the API can return inline or skip, since we have multiple places that only do inline/skip check.
* I'll move ```skipfiles.check``` to ```trace_rules.check``` as one of the follow-ups.
* Both functions consulte ```trace_rules.lookup_inner``` to get the tracing rule.
To avoid a single big PR, I left a few items as the follow-ups:
* Remove ```skipfiles.py``` and merge the code into ```trace_rules.py```.
* We do double check in ```symbolic_convert.check_inlineable```, will refactor and simplify it. We should only do inline/skip check before generating ```SkipFilesVariable``` and ```UserFunctionVariable```.
* Rename ```SkipFilesVariable``` as ```SkipFunctionVariable```, since we only handle functions.
* The inline/skip reasons are not logged for some cases, since the new lookup framework doesn't always return inline/skip reasons. I'll refactor loggings to record the inline/skip reason in next step.

I was just playing around with improving the typing of symbolic_shapes. The PR is not "complete" but I in particular wanted to get feedback on whether or not people liked making ValueRanges Generic; it seems that distinguishing if you have an Expr ValueRange or a SympyBoolean ValueRange is a lot of trouble for downstream. Using TypeGuard, we can perform refinements on the generic parameter inside methods, although we still have to cast back to ValueRange[T] due to https://github.com/python/mypy/issues/14425#issuecomment-1914852707

We split install_global_once into two APIs:
- `install_global_by_id(prefix, value) -> name`: installs a global if it hasn't
been installed yet
- `install_global(prefix, value) -> name`: always installs the global (and
generates a unique name for it)
Then, we refactor most callsites of `install_global_unsafe` to one of
the previous. Some callsites cannot be refactored because we create the
global name first, do a lot of stuff with it, and then install it.
This fixes more test flakiness.
Test Plan:
- Existing tests; I can't reliably repro the flakiness

Previously, if someone wrote a python abstract impl but didn't import
the module it is in, then we would raise an error message suggesting
that the user needs to add an abstract impl for the operator.
In addition to this, we suggest that the user try importing the module
associated with the operator in the pystub (it's not guaranteed that
an abstract impl does exist) to avoid confusion.
Test Plan:
- new test

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.
