If we are hitting a size limit for PGO, then we need to reduce the size of _PyEval_EvalFrameDefault, to let the compiler do its job.
Force inlining stuff is not going to help.
Reverting https://github.com/python/cpython/pull/25244 for 3.10 seems to be the cleanest way to do this.
Would someone with a reliable way to test performance on Windows test the effect of https://github.com/python/cpython/pull/28475, please?
Longer term we need get PGO in MSVC working on larger functions, but I doubt that will be possible for 3.10.
