    See this thread: https://github.com/llvm/llvm-project/pull/145565#issuecomment-3004861443

This PR added new `llvm-lit` tests for `clang-cl`. The PR CI jobs were green, but after merging, it was found that this broke Solaris buildbot.

This issue is for finding a way to detect this problem during PR CI jobs, so that breaks can be found before merging.
