Brad King 3d8356d486 Clang: Support Windows variants for GNU and MSVC (#13035 , #14458 )

Teach the compiler identification preprocessor tests to report when
Clang simulates MSVC, and what version.  If not MSVC, assume GNU.

Teach compiler information modules Clang-(C|CXX) to recognize when Clang
simulates MSVC and skip loading the GNU information.

Teach the Windows-MSVC platform information to recognize when it is
loaded as the simulated compiler and use that version information
instead of the real compiler's (different) version scheme.

Add platform modules Windows-Clang-(C|CXX) and support module
Windows-Clang to load either Windows-MSVC or Windows-GNU and wrap
the corresponding information macros.
