No, we don't reland broken changes in main in llvm-project. Add a revert of https://github.com/llvm/llvm-project/commit/d357324f7700188c9ef179a4bc7898079cf49b6f in your PR #87016 first, with the fix either as a distinct reviewer which is squashed when merging (a nice touch for reviewers to see what's new in the reland), or just have 1 commit which is this PR + the fixup squashed (less easy for reviewers to see what's different).
