Complementing https://reviews.llvm.org/D76786, this patch enables the MVEGatherScatterLowering pass to build pre-incrementing scatters.
If the increment (i.e., add instruction) that is merged into the scatteris the loop increment, an incrementing write-back scattercan be built, which then assumes the role of the loop increment.
