Ryan C. Gordon 9f56c7cf02 audio: Remove 5.1->X SIMD converters, add SSE mono->stereo. 
The 5.1 versions didn't use the new algorithm, and making that new
algorithm work took so many permutes that it was significantly slower
than just using the scalar versions.

However, mono-to-stereo is an extremely common conversion, and it's
trivial to accelerate it with plain SSE, so that was added!
