d = vec_cmpeq_or_0_idx(a, b)Returns the lowest byte-index of comparing each set of corresponding elements of the given vectors for equality, and comparing each elements of a against 0. If the two vectors are not equal, and no elements of a is 0, the result is 16.
The result is placed into byte element seven of the returned vector, and all other bytes are set to 0.
