tree-vect-transform.c (get_initial_def_for_reduction): Set need_epilog_adjust back to false for MIN/MAX case.

        * tree-vect-transform.c (get_initial_def_for_reduction): Set
        need_epilog_adjust back to false for MIN/MAX case. Set *scalar_def to
        NULL if need_epilog_adjust is false.
        (vect_create_epilog_for_reduction): Variable adjust_in_epilog removed.
        Case 3 always peels first itration, not just for PLUS case, and no need
        to use scalar_initial_def here. Create an epilog adjustment only if
        scalar_initial_def is not NULL.

        (vectorizable_reduction): Remove assert.
