Good luck with the reland :)

Please watch http://lab.llvm.org:8011/console after committing.
http://lab.llvm.org:8011/builders/clang-x86_64-debian-fast cycles pretty
quickly.

(Sadly, I'm not aware of a quick-cycling mac bot running macOS on that
waterfall. Maybe there is one and I just don't know about it though.
There's a mac bot on http://45.33.8.238/ but it uses GN and it might be
broken due to unrelated things. If it isn't, it cycles in ~8 minutes
though. IIRC the bot was able to auto-merge the cmake changes in this
change the last time it landed, so maybe you can look at that for the
reland.)
