  Log Message:
  -----------
  Greedy: Simplify collectHintInfo using MachineOperands. NFCI. (#159724)

If a COPY uses Reg but only in an implicit operand then the new
implementation ignores it but the old implementation would have treated
it as a copy of Reg. Probably this case never occurs in practice. Other
than that, this patch is NFC.
