On arches where long double is the same as double, alias ceil(), floor()

Browse Source 
and trunc() to the corresponding long double functions.  This is not
just an optimization for these arches.  The full long double functions
have a wrong value for `huge', and the arches without full long doubles
depended on it being wrong.
