Thanks @craig.topper for spotting the bugs with the dominator tree and setting GEPs inbound. I've fixed those, plus removed the redundant PHI from the scalar loop preheader. I still see the same performance improvements for the loops we care about. I realise I haven't addressed all of your comments - we will try to address them later!
