I've been trying to apply some portions of it to RISCV vectors. So far just the code to push computations out of the loop. One interesting thing I noticed is that MVEGatherScatterLowering can't push shl by a constant splat out of a loop. That would be the canonical IR for a multiply by a constant power of 2 splat.
