***********************************************************************
* The following 2 functions ('cal_nmvjointsadcost' and *
* 'cal_nmvsadcosts') are used to calculate cost lookup tables *
* used by 'vp9_diamond_search_sad'. The C implementation of the *
* function is generic, but the AVX intrinsics optimised version *
* relies on the following properties of the computed tables: *
* For cal_nmvjointsadcost: *
* - mvjointsadcost[1] == mvjointsadcost[2] == mvjointsadcost[3] *
* For cal_nmvsadcosts: *
* - For all i: mvsadcost[0][i] == mvsadcost[1][i] *
* (Equal costs for both components) *
* - For all i: mvsadcost[0][i] == mvsadcost[0][-i] *
* (Cost function is even) *
* If these do not hold, then the AVX optimised version of the *
* 'vp9_diamond_search_sad' function cannot be used as it is, in which *
* case you can revert to using the C function instead. *
