Thanks a lot for taking this over! Looks good from my side but you may wish to wait for a more expert review.

I also confirmed that this still fixes our issue on the 10.0 branch. I had to remove `-scev-cheap-expansion-budget=1` since that didn't exist in 10, but fortunately it's not needed there. Since it wasn't a clean merge, I put the diff in P8220 <https://reviews.llvm.org/P8220> if it makes your/Tom's life easier.
