New pull request for https://github.com/llvm/llvm-project/issues/89443 The previous PR was reverted after breaking fullbuild due to a missing struct declaration, which I forgot to commit. Reverts revert and adds the missing pthread_rwlockattr_getkind_np / pthread_rwlockattr_setkind_np functions and tests respecitvely.
