Implements #93753 - move frame local guard accessors to C++. Before, we used dict accessors on a Python dict representing the frame's fastlocals that we manually build. We move this accessor to C++ and additionally use the fastlocal index whenever possible. Some implementation notes: - `FrameLocalsMapping` is now initialized as a C++ vector of `PyObject`s. We do not just use the frame's localsplus/fastlocals buffer because we also unbox cells. - `FrameLocalsMapping` can still be converted into a Python dict representing the frame's fastlocals, but it is done lazily. - We update `LeafGuard`, `GuardAccessor`, and `GuardManager`'s `check_nopybind` methods to accept `FrameLocalsMapping`. By default, we convert the `FrameLocalsMapping` to a Python dict and run the original `check_nopybind` on it, but in some cases, conversion is not needed. - We add a new guard accessor `FrameLocalsGuardAccessor`, which is similar to `DictGetItemGuardAccessor` but has special handling for `FrameLocalsMapping`. We create a separate class to emphasize different use cases, but we could probably combine these two (can do in a follow up) dynamo_guard_eval.py microbenchmark update: - 713.2us -> 630.0us (3.10) - 598.8us -> 530.7us (3.12) Other followups: - Add `FrameLocalsMapping` version for `check_verbose_nopybind` in order to match behavior between `check_nopybind` and `check_verbose_nopybind`. This can prevent difficult debugging situations where guards fail (`check_nopybind` returns false) but no guard error message is generated (`check_verbose_nopybind` succeeds). - Rewrite the `SHAPE_ENV` guard into C++ - it is a fairly common guard that results in `FrameLocalsMapping` needing to convert to a dict Pull Request resolved: #140063 Approved by: https://github.com/jansel ghstack dependencies: #142117, #142430
