Intel folks, can you upgrade your build of Clang main to
https://github.com/llvm/llvm-project/commit/4527fba9ad6bc682eceda603150bfaec65ec6916?
The current revision is broken and unrelated changes are getting
notified. There might be one more regression that I am looking into, so
consider not going further than that revision.
Cheers,
Nathan
