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.
