Hey! Sorry about the failing test I just pushed https://github.com/llvm/llvm-project/commit/2767ff49955fc3749d79738820285f152fb55ee9 without rebasing first, so it didn't pick up the recent changes. That's why we're getting the NYI AAPCS bit-fields error in bitfields_be.c.

I'll clean this up now going to remove the error emission and just leave a NYI marker so it behaves as a missing feature, not a hard failure.
