        * tree-vect-data-refs.c (vect_get_smallest_scalar_type): Always
        use gimple_expr_type for load and store calls.  Skip over the
        condition argument in a conditional internal function.
        Protect use of TREE_INT_CST_LOW.

        In case of outer loop vectorization, check for backward dependence
        at the inner loop if outer loop dependence is reversed.
