Fix min_vec_size.ll test for changes in vector-combine (#145392)

Browse Source 
Running the `vector-combine` pass on this test now produces a single
shuffle on a loaded `<1 x float>` instead of an insert into a `<2 x
float>` followed by a shuffle.

This test change matches changes in other tests in PR #144690, which
introduced the optimization.
