[PATCH] [CMake] Don't pass in MSVC warning flags as definitions

[Reid Kleckner]

I think clang_compile only needs to pass down some of CMAKE_C_FLAGS in MSVC mode. For example, /D, /U, and /O2 are all translated correctly here. Other than those flags, I don't think it needs to do anything. Let me try to write a patch for that.
