Optimize imExp #169

It seems that the current SSE3 code is especially good at computing the 
imaginary exponent, using the precomputed table. The idea is to use the same 
idea but to be used by all modes (i.e. using only standard C99 means).

That would increase the performance of sparse version (keeping the maximum 
portability), but also give slight improvement to other modes.
