Though you can't lookup a setter for al final field directly, you can
Field f = T.class.getDeclaredField("t");
MethodHandle setter = MethodHandles.lookup().unreflectSetter(f);
But it doesn't matter much, since MH field getters/setters are baseon on
Unsafe. So, if final field value tracking works for Unsafe, it works for
j.l.i as well.
