[FFmpeg-devel] [PATCH 0/2] Let wmalossless use 16-wide DSPs

This is my take on the case order=8. If that's the only case where it
is not a multiple of 16, then that's probably not worth it.

The scalarproduct_and_madd_int16 originally required orders that are
multiple of 16. wmalossless pro samples sometimes have an order of 8.

The patchset first changes wmalossless by having padded buffers, so as
to be able to use again 16-wide DSP, then restore the 16-wide
constrain in them.
