1dac8fea05 Enables back the mmx/sse optimized version of the vp3 idct. 
It generates different md5sum than the reference C implementation,
but no visual difference, so enabled only when bitexact is not set.

the trick is from various places (my own code in libpostproc, a patch on the x264 list, ...)
