Remove usage of predict buffer for decode Instead of using the predict buffer, the decoder now writes the predictor into the recon buffer. For blocks with eob=0, unnecessary idcts can be eliminated. This gave a performance boost of ~1.8% for the HD clips used. Tero: Added needed changes to ARM side and scheduled some assembly code to prevent interlocks. Patch Set 6: Merged (I1bcdca7a95aacc3a181b9faa6b10e3a71ee24df3) into this commit because of similarities in the idct functions. Patch Set 7: EC bug fix.
