uint8_t VP8ThreadData::non_zero_count_cache[6][4]

This is the index plus one of the last non-zero coeff for each of the blocks in the current macroblock.

So, 0 -> no coeffs 1 -> dc-only (special transform) 2+-> full transform

uint8_t VP8ThreadData::left_nnz[9]

For coeff decode, we need to know whether the above block had non-zero coefficients.

This means for each macroblock, we need data for 4 luma blocks, 2 u blocks, 2 v blocks, and the luma dc block, for a total of 9 per macroblock. We keep the last row in top_nnz.
