[PD] partconv optimization

[Hans-Christoph Steiner]

I think the mac/fink builds of FFTW do use SSE2, since that is the  
minimum that a Mac/Intel has.  I believe SSE2 is required to run Mac/ 
Intel.

As for more optimizations, I would like to turn those on for the whole  
Pd-extended builds, but the strict-aliasing errors need to be fixed in  
order to do that.  If you want to make this happen quicker, you could  
check the archives about the strict aliasing errors, and submit fixes  
to the patch tracker.
