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.
