Adding SSE2 support should be relatively trivial (just a matter of
changing the pshufb [mask_mix] with something else), patch welcome.

<Rodeo> for consistency with the rest, MODE_7_1_FRONT_CENTER would be AV_CH_LAYOUT_7POINT1_WIDE_BACK (since LS+RS is mapped to back channels in other modes)

<Rodeo> sorry, I meant MODE_7_1_REAR_SURROUND would probably be AV_CH_LAYOUT_7POINT1

Introduce 2 additional registers for stride3 and mstride3 to allow
direct accesses (lea drops).

Fixes invalid reads and crashes in vp90-2-05-resize.webm and fuzzed6.ivf.
The output is still not identical to what libvpx does (because we don't
actually scale in MC).

Prevents some invalid memory accesses after resolution change in
vp90-2-05-resize.webm, and libvpx does this too.
