Previously, the scaling related to extended quantize range happens in dequantization stage, which implies the coefficients form forward transform are in different scale(4x) from dequantization coefficients This worked fine when there was not distortion computation done based on 8x8 transform, but it completely wracked the distortion estimation based on transform coefficients and dequantized transform coefficients introduced in commit f64725a0 for macroblocks using 8x8 transform. This commit fixed the issue by moving the scaling into the stage of inverse 8x8 transform. TODO: Test&Verify the transform/quantization pipeline accuracy.
