[issue36357] Build 32bit Python on Windows with SSE2 instruction set

New submission from Ma Lin : On windows, it seems 32bit builds (3.7.2/3.8.0a2) don't using SSE2 sufficiently. I test on 3.8 branch, python38.dll only uses XMM register 28 times. The official build is the same. After enable this option, python38.dll uses XMM register 11,704 times. --- a/PCbuil
