Early-terminate in residual writing using stored nnz counts To allow the above, store nnz counts for luma and chroma DC Add assembly functions to find the last nonzero coefficient in a block Overall ~1.9% faster at subme9+8x8dct+qp25 with CAVLC, ~0.7% faster with CABAC Note this changes output slightly with CABAC RDO because it requires always storing correct nnz values during RDO, which wasn't done before in cases it wasn't useful. CAVLC output should be equivalent.
