clang-cl recognizes -mllvm, so it shouldn't need escaping.

And in general, if you find that clang-cl does not recognize a flag, I
recommend prefixing it with -clang:, which causes clang to treat it as a
GCC-style option in the driver instead of escaping it. The short version
is, use /clang:-fblah instead of -Xclang -fblah if possible.
