  Changed paths:
    M clang/lib/Driver/ToolChains/Clang.cpp
    M clang/test/Driver/cl-options.c
    M clang/test/Driver/modules.cpp

  Log Message:
  -----------
  Properly pass modules flags to frontend when using -std=c++20 instead of -std=c++2a.

In passing, also teach the driver to map /std:c++latest to -std=c++20
not -std=c++2a.
