vect: Fix multi-vector SLP gather loads [PR103744]
This PR shows that I didn't properly test the multi-vector case when
adding support for SLP gather loads. The patch fixes that case using
the same approach as we do for non-SLP cases: keep the scalar base
the same, but iterate through the (also multi-vector) vector offsets.
“vec_num * j + i” is already used elsewhere as a way of handling both
the multi-vector SLP case and the multi-vector non-SLP case.
