I split out D115568 <https://reviews.llvm.org/D115568> D115569 <https://reviews.llvm.org/D115569> D115570 <https://reviews.llvm.org/D115570> from this. I think it is better to start from the outside and work back inward, so the LLVM-only commit that previously came before this would actually be the //last// step.
