Subject: clang: introduce CMAKE_<lang>_COMPILER_FRONTEND_VARIANT

This variable is set to GNU on Windows when clang.exe ar clang++.exe is
used, and set to MSVC for clang-cl.exe.

CMAKE_<lang>_SIMULATE_ID is set to MSVC in both cases, as clang defaults
to -fms-compatibility for all command lines on windows.
