    target/104762 - vectorization costs of CONSTRUCTORs

    After accounting for GPR -> XMM move cost for vec_construct the
    base cost needs adjustments to not double-cost those.  This also
    lowers the cost when such move is not necessary.

            * config/i386/i386.cc (ix86_builtin_vectorization_cost): Do not
            cost the first lane of SSE pieces as inserts for vec_construct.
