The 2-D inverse transform X = M1*Z*Transposed_M2 was calculated in 2 steps from left to right: 1. Vertical transform: Y = M1*Z 2. Horizontal transform: X= Y*Transposed_M2 In SIMD, a transpose is needed in vertical transform. Here, switched the calculation order to do it from right to left. In this way, we could eliminate that transpose by writing the intermediate results out to their transposed positions. Change-Id: I34dfe5eb01292f6e363712420d99475e2e81e12c
