Comment(by foobum at gmail.com):

 Think I missed the gist of your question. sse_optimized.cpp implements
 filters and calcCrossCorrStereo for float samples. The asm in the patch
 implements overlap and calcCrossCorr for stereo and multichannel and 16
 bit int samples. The existing MMX filter code works fine so we use that
 for both x86 and x86_64.
