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.

45854df9a5 dcadsp: split lfe_dir cases
The x86 runs short on registers because numerous elements are not static.
In addition, splitting them allows more optimized code, at least for x86.

This allows masking CPU features with the -cpuflags avconv option
which is useful for testing different optimisations without rebuilding.
