  -----------
  [AMDGPU] Check a wide copy dst reg against the dst operand's regclass (#221789)

The wide-copy check added in #214561 tested the destination against the
source operand's class. No test change: V_MOV_B64's source class VS_64
also accepts a VGPR destination, which is why it currently works. Adding
