   --  to a formal (of a subprogram or entry), and if so returns the Id

   --  reason that this is in Exp_Ch2 is that it has to deal with the
   --  case where the reference is to an entry formal, and has been
   --  expanded already. Since Exp_Ch2 is in charge of the expansion, it
   --  is best suited to knowing how to detect this case.
