        (Note_Redundant_Use): Diagnose a redundant use within a subprogram body
        when there is a use clause for the same entity in the context.
        (Analyze_Subprogram_Renaming): A renaming_as_body is legal if it is
        created for a stream attribute of an abstract type or interface type.

        * sem_dist.ads, sem_dist.adb (Is_RACW_Stub_Type_Operation): New
        subprogram.

        * sem_type.adb
        (Add_One_Interp): Ignore any interpretation that is a primitive
        operation of an RACW stub type (these primitives are only executed
        through dispatching, never through static calls).
        (Collect_Interps): When only one interpretation has been found, set N's
        Entity and Etype to that interpretation, otherwise Entity and Etype may
        still refer to an interpretation that was ignored by Add_One_Interp,
        in which case would end up with being marked as not overloaded but with
        an Entity attribute not pointing to its (unique) correct interpretation.
