[PATCH] D126226: [OpenMP] Add `-Xoffload-linker` to forward input to the device linker

[Fangrui Song via Phabricator via cfe-commits]

MaskRay added a comment.

IIRC there is no built-in way supporting multiple (but fixed number of) values for an option (e.g. `-Xoffload-linker-<triple> <arg>`). In D105330 <https://reviews.llvm.org/D105330> (llvm-nm option refactoring) I used a hack to support `-s __DATA __data`.
The multiple-value support for OptTable does not allow positional arguments after the option.

Consider something like `-Xoffload-linker-triple <triple>=<arg>`
