Framework changes in nzc to allow more flexibility The patch adds the flexibility to use standard EOB based coding on smaller block sizes and nzc based coding on larger blocksizes. The tx-sizes that use nzc based coding and those that use EOB based coding are controlled by a function get_nzc_used(). By default, this function uses nzc based coding for 16x16 and 32x32 transform blocks, which seem to bridge the performance gap substantially. All sets are now lower by 0.5% to 0.7%, as opposed to ~1.8% before. Change-Id: I06abed3df57b52d241ea1f51b0d571c71e38fd0b
