If the semantics match a standard pattern, you should use the standard 
name.

It may well be the case that many of those patterns would not actually be 
used for generic code even after my _FloatN patches, since (a) I only add 
a minimal set of built-in functions, not the full set of all libm 
functions for all _FloatN / _FloatNx types (given possible issues with 
enum size and initialization time when seven new variants of every libm 
function are added as built-in functions) and (b) many relevant 
optimizations only work for float, double and long double.  But I think 
the right pattern names should still be used.
