FWIW, Andy Kaylor's started a review/discussion on disabling some MSVC
warnings and cleaning up others to get a baseline.

This is one I'm sort of inclined to disable (as mentioned in the review
thread & some other recent discussions - the basic bar that's certainly
been applied to GCC and I think is a reasonable one is: If the warning
doesn't meet the quality bar to be added to Clang, then it probably doesn't
meet the quality bar to be enabled for building LLVM projects and we should
just disable the warning rather than fixing it even once)
