clang-tidy job merges with master which can lead to hard to understand errors

[ezyang]

All of the Azure jobs appear to run on /merge rather than the real commit, so they line up with ROCm behavior but not the rest of the behavior. Ordinarily I'd say this was bad... but it actually was good: in #24937 @pearu had a diff which would have caused a GEN_TO_SOURCE failure after merging with master, but the merge-with-master caught it. Except... it was really confusing and hard to tell what was going on, because the error referred to code that literally could not be found in the real copy. There should be some way to make it clearer what's going on here.

We don't do any automated clang-format today, right? Do you mean clang-tidy?

[ezyang]

Yes you're right

Closing this issue as this is not relevant anymore, we now have clang-tidy running as part of lintrunner
