@arsenm I pushed a version which just walks regunit roots, see https://github.com/llvm/llvm-project/pull/164724/files#diff-9aed5b156d320e04c0a60491e5f42e1e9e275052fc148515089bc4796937c0f7R2247

Ignore the rest of the diff for now, I still can't get graphite to update these and need to manually go through and clean up the branches
