method in instance_eval

* class.c (rb_special_singleton_class_of): utility function.
* vm_eval.c (eval_under): special deal for class variable scope with
  instance_eval.
* vm_eval.c (rb_obj_instance_eval, rb_obj_instance_exec): allow method
  definition in instance_eval of special constants.  [ruby-core:28324]
