Remove rate component adjustment for AQ1 In AQ1 a rate adjustment was applied for blocks coded with a deltaq. This tends to skew the partition selection and cause rate overshoot. For example, consider a 64x64 super block where some but not all sub blocks are in a low q segment and some are in a high q segment. The choice of Q when considering large partition and transform sizes is defined by the lowest sub block segment id (currently this implies the lowest Q). If some parts of the larger partition are very hard this will cause a high rate component. The correct behavior here is for the rd code to discard the large partition choice and break down to sub blocks where some have low and some have high Q. However the rate correction factor above mask the high cost of coding at a larger partition size. Change-Id: Ie077edd0b1b43c094898f481df772ea280b35960
