644c32ea4b x86/vp9lpf: add ff_vp9_loop_filter_[vh]_88_16_sse2()

222c46c531 x86/vp9lpf: add ff_vp9_loop_filter_[vh]_88_16_{ssse3,avx}. 
9680 decicycles in loop_filter_v_88_16_c, 4193765 runs, 539 skips
9233 decicycles in loop_filter_h_88_16_c, 4193751 runs, 553 skips

1929 decicycles in ff_vp9_loop_filter_v_88_16_ssse3, 4194118 runs, 186 skips
2738 decicycles in ff_vp9_loop_filter_h_88_16_ssse3, 4193861 runs, 443 skips

5.978 → 5.417 overall decode time on ped1080p.webm (-threads 1)

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

673ce8e46a avcodec/libfdk-aacenc: change MODE_7_1_FRONT_CENTER to map to AV_CH_LAYOUT_7POINT1_WIDE_BACK 
This was suggested by Rodeo on IRC
<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)

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

c9e6325ed9 vp9/x86: use explicit register for relative stack references. 
Before this patch, we explicitly modify rsp, which isn't necessarily
universally acceptable, since the space under the stack pointer might
be modified in things like signal handlers. Therefore, use an explicit
register to hold the stack pointer relative to the bottom of the stack
(i.e. rsp). This will also clear out valgrind errors about the use of
uninitialized data that started occurring after the idct16x16/ssse3
optimizations were first merged.
