0d0642fd67 pcm/PcmFormat: instantiate FloatToInteger<S32> 
.. instead of reusing FloatToInteger<S24> and converting from S24 to
S32 in-place.

afcf0795c4 pcm/Volume: improved dithering 
Instead of just adding a rectangular random value before shifting back
to the normal scale, use the existing PcmDither library.

f3bbe4bb1f pcm/Volume: remove optimized i386 assembly 
This code is unable to dither.  Until we implement that, let's remove
the code for now.  i386 isn't relevant anymore anyway.
