This patch doesn't fix all the issues I've spotted with `selectGatherScatterAddrMode` but because D122994 <https://reviews.llvm.org/D122994>  greatly simplifies the same function, I've restricted my fixes to just those that would exist if that patch landed before this one.  I also believe `refineIndexType` contains a bug although not necessarily one we can realistically hit so am leaving that for a follow-on patch.
