Thanks for the patch! I have a few questions.

Can you explain what you mean by a cross-fork PR? Do you have an example of such a failed job? We regularly create PRs from our own forks of the repo against the main LLVM repo without issue, so I am a bit confused about what problem is being fixed here.
