[PATCH] D103510: [RISCV] Use vmv.v.[v|i] if we know COPY is under the same vl and vtype.

My browser's really chugging on this huge patch so my input has to be brief. Maybe we could hide the test changes for now?

Regarding `vmv.v.i`, is there not already some support for rematerialization (e.g. of immediates)? Or is it non-trivial due to having to manage VSETVLIs?
