I thought that it should not have any merge conflicts and it turned out to be almost true, the only conflict I encountered was in `CMakeLists.txt`, feel free to use this squashed and rebased commit for testing from my fork: https://github.com/ilya-biryukov/llvm-project/commit/e6329b9390445369c537aa6aa5a5cd64ba27e19c
