LGTM with a minor nit, but give a couple days for @jyknight to add any more comments.

Or if that doesn't work for everything, maybe you could share a check prefix for some of the tests? (Maybe it would make sense to check IR generated using `-disable-llvm-passes`.)

You can use something like "-check-prefixes=CHECK,O0" to reduce the duplication.
