[Ada] Further illegalities with operator call in functional notation

[Arnaud Charlet <charlet at adacore dot com>]

With this patch the compiler properly rejects a call of the form P."+" (X, Y)
when X and Y are numeric literals, and the result type is not declared in P.

Compiling the following must be rejected with:

   derived_folded_mistyped.adb:8:27: expect type "T3"
---
procedure Derived_Folded_Mistyped is
   package Scop is
      type T2 is range 1 .. 4;
   end Scop;

   type T3 is new Scop.T2;
   X : constant T3 := Scop."+" (1, 2); --  ERROR: Scop."+" returns T2
begin
   null;
end Derived_Folded_Mistyped;

Tested on x86_64-pc-linux-gnu, committed on trunk
