(** Keep track of the global module Aliases *) 

(**
    One way:  guarantee that all global aliases *would be removed* ,
    it will not be aliased 
    
    So the only remaining place for globals is either 
    just  Pgetglobal in functor application or 
    `Lprim (Pfield( i ), [Pgetglobal])`

    This pass does not change meta  data
