Since JDK-8263424 has refreshed the policy of vector size, there are many useless judgements like `n->in(2)->bottom_type()->is_vect()->length_in_bytes() >= 16 ` in

  predicate(UseSVE > 0 && n->in(2)->bottom_type()->is_vect()->length_in_bytes() >= 16 &&
            n->in(2)->bottom_type()->is_vect()->element_basic_type() == T_BYTE);

This issue will remove these useless judgements in adfile.
