fhahn added a comment.

Thank you very much for having a look Eli and sorry for the delay, I needed to find some time to investigate another failure in the test suite with this change. Together with https://reviews.llvm.org/D45970 and this patch, building the test-suite with LoopInterchange + LTO passes.

I've updated the code to make sure the exiting's block's terminator is a branch instruction.
