This patch will use the dest buffer instead of the predictor buffer. This will allow us in future commits to remove the extra mem copy that occurs in the dequant functions when eob == 0. We should also be able to remove extra params that are passed into the dequant functions. Change-Id: I7241bc1ab797a430418b1f3a95b5476db7455f6a
