    [cc2] Rename addressability() to apply()
    
    Addressability() was basically running over the nodes of the current
    function and calling a function for every statement. This is a general
    function and it is better to pass it the function we can call for
    every statement.
    Since the function is now a generic function, the best place for it
    is in node.c
