(I guess the perf measurement target would be JIT and free-threaded builds if really needed, rather than default builds.) |
I think it might be useful in the future, but if it's not being used it may just bitrot, so probably better to remove it. I'll add that to this PR. |

In earlier versions of MSVC, the compiler would crash when doing a PGO build due to the large size of
PyEval_EvalFrameDefault. This bug has been fixed upstream in MSVC, so we should remove our workaround.While this does re-enable optimizations on
PyEval_EvalFrameDefault, the performance gains on the benchmarks are unfortunately below the measurement threshold. Still worth doing without a performance benefit just to simplify things.
