Thanks @vitalybuka, appreciate it! 

P.S. If there's a guide on how to do "stacked" PRs on Github or otherwise what's the blessed workflow for stacks of changes that'd be very helpful (not much about this in https://llvm.org/docs/GitHub.html). I'd do a stack of diffs in Phabricator but here it's different.
