I have spoken with @spatel who said he is unlikely to have much time to progress this patch and he's happy for me to commandeer it. I would like to make progress on this because it is an important fix on AArch64 for the SPEC2017 benchmark parest.

@nikic do you have any thoughts about whether it's worth re-opening D144274 <https://reviews.llvm.org/D144274> and potentially using the LoopInfo in more places to fix the compile-time issue you saw?
