[RISCV] Fix a silent miscompile in copyPhysReg
Found this when adding verifier rules. The case which arises is that we have a DefMBBI which has a VecPolicy operand. The code was not expecting this, and the unconditional copy of the last two operands resulted in the SEW and VecPolicy fields being added to the VMV_V_V as AVL and SEW respectively.
Oddly, this appears to be a silent in practice. There's no test change despite verifier changes proving that we definitely hit this in existing tests.
