Looks like this got committed in 886715af962de2c92fac4bd37104450345711e4a <https://reviews.llvm.org/rG886715af962de2c92fac4bd37104450345711e4a> though it was missing the `Differential Revision` tag to allow phab (or humans) to connect the commit with the review.
In any case, this seems to be causing a UBSan (`UndefinedBehaviorSanitizer: out-of-bounds-index third_party/python_runtime/v3_9/Objects/codeobject.c:54:34 `) regression in Python 3.9 at Google - I don't have a readily shareable standalone reproduction just now - but would you consider reverting while this is investigated further?
