* Build-in Function
* uintn amd_bitalign (uintn src0, uintn src1, uintn src2)
* Description
* dst.s0 = (uint) (((((long)src0.s0) << 32) | (long)src1.s0) >> (src2.s0 & 31))
* similar operation applied to other components of the vectors.
*
* The implemented function is modified because the last is in our case always a scalar.
* We can ignore the bitwise AND operation.
