I put in the warnings because MSVC has them, but I don't think they're very useful. Clang does not warn about overriding flags in general, e.g. it's perfectly fine to have -fomit-frame-pointer followed by -fno-omit-frame-pointer. We should focus on warning where things get confusing, such as with the /TP and /TC options. In "clang-cl /TC a.c /TP b.cc", the user might not realize that the /TP flag will apply to both files, and we warn about that.
