oh! err hang on - that needed some discussion rather than an
arbitrary decision.  looking at pages 734 onwards in Public v3.1
there are a considerable number of different precision min/max
operations.

>     remove fminmaxs since it's redundant with fminmax

this needs explanation and discussion rather than an unjustified
decision.  remember i have to explain it to the ISA WG and when
they ask the answer cannot be "i haven't the faintest idea why
jacob made that decision" :)
