38 -- Given an expression N, determines if the expression is a reference
39 -- to a formal (of a subprogram or entry), and if so returns the Id
40 -- of the corresponding formal entity, otherwise returns Empty. The
41 -- reason that this is in Exp_Ch2 is that it has to deal with the
42 -- case where the reference is to an entry formal, and has been
43 -- expanded already. Since Exp_Ch2 is in charge of the expansion, it
44 -- is best suited to knowing how to detect this case.
