b385c4c6a3 x86/swr: replace sse4 instructions in pack_6ch with sse ones 
There's no benefit from using blendps here except on CPUs with AVX, where
it's faster than shufps according to Intel's documentation.
As such, rename the sse4 functions to sse/sse2 and use shufps instead.

2c5c37ade1 libswresample: move condition to start of loop. 
This avoids several issue like calculating sum/maxcoef
incorrectly due to adding up matrix entries that will
be overwritten, as well as out-of-range writes to
s->matrix if the maximum allowed number of channels is used.

2231d5b671 libswresample: Avoid needlessly large on-stack array. 
We only actually need to use a tiny part of it.
Unfortunately we seem to have no real test coverage on
