Simplify mask checking in loop filters Considering a horizontal edge, if mask_16x16 is 1 for an even- indexed 8x8 block, then mask_16x16 is 1 for next 8x8 block in same row. Similiar to a verticle edge, if mask_16x16 is 1 for an even-rowed 8x8 block, then mask_16x16 is 1 for the 8x8 block right below it in next raw. Based on that, the mask_16x16 checking can be simplified to save cycles. The corresponding 8-pixel vp9_mb_lpf_horizontal_edge code can also be removed.
