on entries, entry families, subprograms and generic subprograms.

Minor code reorganization to ensure that the Ekind attribute
of the subprogram entity is set before its formals are
processed. Required to allow the use of the attribute
Has_Out_Or_In_Out_Parameter on the subprogram entity.

enclosing construct.
