Optimized version of powf()
Most significant changes are code simplification and use of doubles for intermediate values. Also, some rearrangement to move early non-dependent code later, out of the faster paths. * sysdeps/ieee754/flt-32/e_powf.c: Optimized implementation utilizing rearranged code and doubles float types.
