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.

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.
