7686afd049 dca: factorize scaling in inverse ADPCM 
Based on a patch from Christophe Gisquet.

Unrolling of the m == 0 case avoids a possible use of the uninitilized
value sum when s->predictor_history is not set. I failed to find a
sample for it. It also reduced the cycle count from 220 to 150 on
sandy bridge, x86_64 linux, gcc 4.8.2 compared to his patch.

08e3ea60ff x86: synth filter float: implement SSE2 version 
Timings for Arrandale:
          C    SSE
win32:  2108   334
win64:  1152   322

Factorizing the inner loop with a call/jmp is a >15 cycles cost, even with
the jmp destination being aligned.

Unrolling for ARCH_X86_64 is a 20 cycles gain.

87ec849fe9 dcadec: remove scaling in lfe_interpolation_fir 
The scaling factor is constant so it is faster to scale the
FIR coefficients in the tables during compilation.
