212b78aa - DAG: Improve fminimum/fmaximum vector expansion logic (#93579)

DAG: Improve fminimum/fmaximum vector expansion logic (#93579) First, expandFMINIMUM_FMAXIMUM should be a never-fail API. The client wanted it expanded, and it can always be expanded. This logic was tied up with what the VectorLegalizer wanted. Prefer using the min/max opcodes, and unrolling if we don't have a vselect. This seems to produce better code in all the changed tests.
