1713 * For cal_nmvjointsadcost: *
1714 * - mvjointsadcost[1] == mvjointsadcost[2] == mvjointsadcost[3] *
1715 * For cal_nmvsadcosts: *

1717 * (Equal costs for both components) *
1718 * - For all i: mvsadcost[0][i] == mvsadcost[0][-i] *
1719 * (Cost function is even) *
1720 * If these do not hold, then the AVX optimised version of the *
1721 * 'vp9_diamond_search_sad' function cannot be used as it is, in which *
