Yeah, I don't think this was rebased in several months, otherwise, I'd expect a conflict between ToT and this patch. 

If the comment about round tripping the operand bundle through bitcode and back to IR is still relevant, we should probably add a test, and update any bug tracking though. @Prabhuk would you mind following up on that part, since it seems like the functionality you're after is already in tree?
