b57e38f52c ac3dsp: x86: Replace inline asm for in-decoder downmixing with standalone asm
Adds a wrapper function for downmixing which detects channel count changes
and updates the selected downmix function accordingly.

Simplification and porting to current x86inc infrastructure by Diego Biurrun.

43717469f9 ac3dsp: Reverse matrix in/out order in downmix()
Also use (float **) instead of (float (*)[2]). This matches the matrix
layout in libavresample so we can reuse assembly code between the two.

7c00e9d8ae x86: ac3dsp: Remove 3dnow version of ff_ac3_extract_exponents
The function requires increasing the fuzz factor for the ac3/eac3 encode
tests and even so makes fate fail. It only provides a slight encoding
speedup for legacy CPUs that do not support SS2. Thus its benefit is not
worth the trouble it creates and fixing it would be a waste of time.

3e15775333 x86/ac3dsp_init: try to workaround ICC failure.
The asm code is not valid for older compilers as it uses too many
operands, ICC on x86_32 seems affected by this.
This patch disables the affected code for ICC on x86_32 and should
make it compileable again.
A better fix would be to use fewer operands or to change this code
to yasm, later is being worked on AFAIK so this is a temporary
solution.
