LGTM, thank you for all the hard work on this! I assume you need me to land this on your behalf -- if so, can you let me know what name and email address you would like me to use for patch attribution?

I think we should add a release note for this to let folks know about the new warning group (there's a "Improvements to Clang's diagnostics" in clang/docs/ReleaseNotes.rst). You can either add one to this patch, or I can add one for you when I go to land, I'm fine either way.
