This change caused build bot failure for MacOS and the PR got reverted.

The reason that on MacOS the hash is different is that there is an extra option `-mlinker-versioin=` which is added by clang (https://github.com/llvm/llvm-project/blob/main/clang/lib/Driver/Driver.cpp#L515).

Since the hash is toolchain dependent, it seems we cannot hardcode it here and has to keep it as it was.

@Artem-B If you are OK, I will reland the patch with "-cuid=[[CUID:[0-9a-f]+]]" here.
