I was looking at this earlier to try and figure out what is right. I think this looks OK, but the NumMicroOps should still be 1. In practice there might be a different resource, but it is not going to be super accurate with it taking a data-dependant number of cycles.

Can we change the vector and sve divides at the same time?
