  [LiveRangeEdit] Remove any MemoryOperand on MI when converting it to KILL. (#114407)

When LiveRangeEdit::eliminateDeadDef() converts an MI to a KILL instruction,
it should also call dropMemRefs() in order to erase any MachineMemOperand
present.

This was discovered in testing as the MachineVerifier does not accept an MMO
without the corresponding MI mayLoad/mayStore flag, which the KILL opcode
lacks.
