Extend left/above partition context to per mi(8x8) Update and buffer left/above partition information context per 8x8 block. This allows to further enable recursive partition down to 4x4 block size, and hence deprecating I4X4_PRED and SPLITMV. This commit also fixes a context buffer swap/restore issue in 32x32 partition type search. This gives 0.1% performance gain for derf/yt. Will refactor the superblock partition type search into recursion form. Change-Id: Ib61975aca5f12b78d8018481d7fa1393d085689b
