LLVM_ON_WIN32 is set exactly with MSVC and MinGW (but not Cygwin) in HandleLLVMOptions.cmake, which is where _WIN32 defined too. Just use the default macro instead of a reinvented one. See thread "Replacing LLVM_ON_WIN32 with just _WIN32" on llvm-dev and cfe-dev. No intended behavior change. This moves over all uses of the macro, but doesn't remove the definition of it in (llvm-)config.h yet. llvm-svn: 331127
