010732b73a vp9/x86: simplify FILTER_INIT. 
In the 2 FILTER_INIT usages, the source is already preloaded so that
extra complexity taken from FILTER_UPDATE is not necessary.

Also add forgotten "mask" argument in FILTER_{INIT,UPDATE} comments.

669d4f9053 x86/vp9lpf: simplify 2nd transpose in 44/48/88/84. 
For non-avx optims, this saves 8 movs.

9680 decicycles in loop_filter_v_88_16_c, 4193765 runs, 539 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.

5d144086cc x86/vp9lpf: faster P7..Q7 accesses. 
Introduce 2 additional registers for stride3 and mstride3 to allow
direct accesses (lea drops).

3931 → 3827 decicycles in ff_vp9_loop_filter_v_16_16_ssse3

Also uses defines to clarify the code.
