  [SVE] Fix incorrect offset calculation when rewriting an instruction's frame index. (#70315)

When partially packing an offset into an SVE load/store instruction we
are incorrectly calculating the remainder.

  [RISCV] Correct copyPhysReg for GPRPF64. (#70419)

GPRF64 represents a pair of registers. We were only copying the even
part. We need to copy the odd part too.
