The refineIndexType & refineUniformBase functions added by D90942 <https://reviews.llvm.org/D90942> can also be used to
improve CodeGen of masked gathers. This patch also changes SplitVecRes & SplitVecOp for
MGATHER to split the type returned by getMemoryVT() before creating the Hi & Lo masked gathers.

These changes were split out from D91092 <https://reviews.llvm.org/D91092>
