I think the "RFC" prefix for this series can be dropped. :)
It looks to me like all of Peter's concerns have been addressed. I'd say let's get the Clang side landed, and once that's done, land this via x86 -tip?
Peter and Will does this sound right to you? It touches arm64, so if -tip isn't okay, I could take it in one of my trees?
