Maybe a nicer way of threading through the allowed pseudos is by passing through the list of allowed VTypeInfos? I think we already do this for `VPatBinarySDNode_VV_VX`, so something like

```suggestion
multiclass VPatBinaryFPSDNode_VV_VF_RM<SDPatternOperator vop, string instruction_name, list<VTypeInfo> vtilist,
                                       bit isSEWAware = 0> {
  foreach vti = vtilist in {
```
