Yep, the latter. We use it here because the ISD node exists for other reasons
and so was convenient to reuse here.
In general the main reason to create `FAMAX_PRED` is when there's optimisation
to be had. In this instance I think it's more likely for us break the
operation into separate FABS_PRED/FMIN_PRED nodes to let the combiner at it,
given it'll be easy to reconstruct the `famin` during isel.
