[PATCH] D142757: [clang][driver] Emit an error for `/clang:-x`

[Aaron Ballman via Phabricator via cfe-commits]

aaron.ballman added a comment.

This seems reasonable to me. I was a bit worried about the behavior being rather strange, but given that these are "escape hatch" command line options to skip the clang-cl driver, and there are existing clang-cl options that cover this functionality, it makes more sense to me now. LGTM, but please add a release note about the fix (to clang/docs/ReleaseNotes.rst). I'll leave the final sign-off to @MaskRay.
