tra added a comment.

> I would be ok with reusing that option, as long as it's documented that there is a difference in terms of how it can be used.

The patch is in https://reviews.llvm.org/D57487
It does not look like we're formally documenting CC1 options anywhere. I've added some comments next to SDKVersion in TargetOptions.h. PTAL.
