bswap.h: Remove unused float-access functions

Browse source 
The float-access functions stfl_*, stfq*, ldfl* and ldfq* are now
unused; remove them. (Accesses to float64 and float32 types can be
made with the ldl/stl/ldq/stq functions, as float64 and float32 are
guaranteed to be typedefs for normal integer types.)
