    rs6000: Fix an assertion in update_target_cost_per_stmt [PR103702]

    This patch is to fix one wrong assertion which is too aggressive.
    Vectorizer can do vec_construct costing for the vector type which
    only has one unit.  For the failed case, the passed in vector type
    is "vector(1) int", though it doesn't end up with any construction
    eventually, we have to handle this kind of possibility.
