Commit 12cd6f42 authored by Dmitry Kovalev's avatar Dmitry Kovalev

Removing variance MMX code.

Removed functions:
* vp9_mse16x16_mmx
* vp9_get_mb_ss_mmx
* vp9_get4x4var_mmx
* vp9_get8x8var_mmx
* vp9_variance4x4_mmx
* vp9_variance8x8_mmx
* vp9_variance16x16_mmx
* vp9_variance16x8_mmx
* vp9_variance8x16_mmx

They all have SSE2 equivalent.
