Forward hierarchy_of_t in nt2
Made as_size independant of dispatch
Fix usage of as_size in deltac/deltaf
correct fma has to ensure 'no intermediate overflow'
This is done in the case of signed integers by transtyping to unsigned type and back
using multiplies correct the unsigned short overflow problems with fnma and fnms
Remove spurrious include for auto/decltype
