[PATCH] D135076: [Clang] Make offloading flags accept '-' and '--'

[Fangrui Song via Phabricator via cfe-commits]

MaskRay added a comment.

We really want these `--offload-*` users to stick with one canonical form, not `-offload-*` in some places while `--offload-*` in other places.

Another angle is that people find `-offload-*` working with a new clang may try `-offload-*` on an old clang and get `-o ffload-*`.
