I'm going to take another look at this bug.
I've also uploaded a couple of other fixes for SubRange join failures. See https://reviews.llvm.org/D40300 and https://reviews.llvm.org/D40308. I've also uploaded a verifier method that is helpful in tracking these problems down. See https://reviews.llvm.org/D40297.

@arsenm you might find one of these changes also fixes your issue. Let me know if you try them and it does (or doesn't).
