New Revision: b96b9335aea5fc9092cb4ec7df9152ff9b9db3dc
URL: https://github.com/llvm/llvm-project/commit/b96b9335aea5fc9092cb4ec7df9152ff9b9db3dc

LOG: Use more LLVM_ENABLE_ABI_BREAKING_CHECKS in Error.h
Summary:
If we don't read the flag, we don't need to set it. Then we also don't
need to filter it out to get the pointer.
This should have a (small) positive impact on code size and performance.
