+ __builtin_convertvector((__v4si)__A, __v4qi), (__v4qi){0, 0, 0, 0}, 0, 1,
+ 2, 3, 4, 5, 6, 7, 7, 7, 7, 7, 7, 7, 7, 7);

If you need to add more zeroes than the width of the input, can you just repeat
the zero vector in order as many times as necessary. It should look more like a
concatentation.
so 0, 1, 2, 3, 4, 5, 6, 7, 4, 5, 6, 7, 4, 5, 6, 7
