[issue39521] reversed(mylist) much slower on Python 3.8 32-bit for Windows

[Steve Dower]

Steve Dower <steve.dower at python.org> added the comment:

Just FYI, there is no PGO run on the official 32-bit builds. I only run it on the 64-bit build.

It might be worth investigating differences between the 3.7 and 3.8 implementations of reversed().
