Sorry I wasn't clear. I just meant to use the existing code but add OperandType and OperandNamespace at the end together
```
// A vector move shifter operand:
//  {0} - imm1: #8 or #16
def move_vec_shift : Operand<i32> {
  let PrintMethod = "printShifter";
  let EncoderMethod = "getMoveVecShifterOpValue";
  let ParserMatchClass = MoveVecShifterOperand;
  let OperandType = "OPERAND_MSL_SHIFT";
  let OperandNamespace = "AArch64";
