Chandler Carruth 4c1b05f822 Make the User::value_op_iterator a random access iterator. I had written 
this code ages ago and lost track of it. Seems worth doing though --
this thing can get called from places that would benefit from knowing
that std::distance is O(1). Also add a very fledgeling unittest for
Users and make sure various aspects of this seem to work reasonably.
