Michael Niedermayer 4977692461 swresample: Choose 16bit internally only if input and output is 16bit or less 
or if no rematrix and no resampling is performed and the input is 16bit
note reampling and rematrix itself always use more than 16bit internally
the "internal" sampling format is the format between these steps

Its unlikely the difference from this commit is audible in any case
unless there is some bug either before or after the change.
but multiple people prefer this and it slightly improves the precission
of computations.

James Almer 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.
