How about:
```
  case Intrinsic::aarch64_sve_fmin_u:
    return DAG.getNode(AArch64ISD::FMIN_PRED, SDLoc(N), N->getValueType(0),
                       N->getOperand(1), N->getOperand(2), N->getOperand(3));
```

Should it also not use a custom ISD node? Or we use here it because we have it anyway? (for lowering `ISD::FMINIMUM` ?)
