Maybe worth explicitly mentioning in the commit message that AggressiveDeadCodeElimination::updateDeadRegions loops over BlocksWithDeadTerminators.

It's fine to commit non-determinism patches without a test, I think, because it's hard to write a useful regression test for these issues.  I mean, you could theoretically CHECK the use-list itself, but that isn't really productive.
