    Clang: Add separate "AppleClang" compiler id · ab658624
    Brad King authored
    Apple distributes their own Clang build with their own version numbers
    that differ from upstream Clang.  Use the __apple_build_version__ symbol
    to identify the Apple Clang compiler and report the Apple Build Version
    as the fourth version component in CMAKE_<LANG>_COMPILER_VERSION.  Add
    Compiler/AppleClang-<lang> and Platform/Darwin-AppleClang-<lang> modules
    that simply include the upstream equivalents.
    Fix comparisons of CMAKE_<LANG>_COMPILER_ID to Clang in CMake's own
    source and tests to account for AppleClang.
