feature.

Ugh, something went tragically wrong with Phabricator's diff display here for some reason. https://reviews.llvm.org/file/data/in2yitrbhop3rtr6ypig/PHID-FILE-qctkyjkcaytlepm3qxe6/D126828.diff looks much better ... could you confirm that it matches the changes you have?

That's what's up now. Back to no context. I'll just resubmit with arc.
