  Changed paths:
    M crypto/bn/rsaz_exp.c
    M crypto/ec/ecp_nistz256.c
    M crypto/ec/ecp_sm2p256.c
    M include/internal/common.h

  Log Message:
  -----------
  Move ALIGN32 and ALIGN64 into common.h, and fix for clang-cl.exe

clang-cl.exe defines __clang__ and _MSC_VER but not __GNUC__, so a clang-
specific guard is needed to get the correct ALIGNxx versions.

Fixes #21914
