I'm not sure this may actually help, but I also did some generic
optimizations, in addition to x86 ones here:
https://github.com/kurosu/libav/commits/dcadsp

I probably won't have much time in the coming weeks to follow up on
this, but there are things that might be of interest.

For instance, I wasn't able to find samples exercising dca_lfe_fir
with resampling, and the code becomes a lot simpler on x86 if each
case is split.
