        Thanks for clearance Dmitry.
        So the difference is only that in the MMX version
        RH_AMP and RH_VALIDATE_MS are enabled.

        RH_AMP stuff is what was previously known as RH_NOISE_CALC
        RH_VALIDATE_MS avoids to switch from LR to MS when
        the perceptual entropy indicates a need for more bits
        in MS coding mode than in LR mode.
