           Summary: Missing MSVC compiler flaga

clang-cl is currently missing the following compiler flags that are available
in MSVC:

/Zf - A fairly new and recent flag added to MSVC in a Visual Studio 2019
update, when set, this preps PDB generation for compilation with /MP. I believe
this does it without forcing serialization.

/LD[d] - This flag is just an alias for /MD[d] for compilation and /DLL for the
linker. /M[TD][d] overrides the /MD[d] set by this flag.
