Since LLVM/Windows emulates Visual Studio, CMake sets CMAKE_C_SIMULATE_ID="MSVC" but does not set MSVC. Thus, our build system needs to enable most (but not all) of the Visual Studio features when CMAKE_C_SIMLUATE_ID="MSVC". Support for LLVM/Windows is currently undocumented because it isn't a standalone build environment. (It requires the Visual Studio and Windows SDK headers and link libraries.) Closes #786
