-- Given an expression N, determines if the expression is a reference
-- to a formal (of a subprogram or entry), and if so returns the Id
-- of the corresponding formal entity, otherwise returns Empty. The
- -- 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.
