[Ada] Suppress warnings on unreferenced parameters of dispatching ops
If the -gnatwf switch is used to activate warnings on unreferenced
formal parameters, the warning is no longer given if the subprogram is
dispatching, because such warnings tend to be noise. It is quite common
to have a parameter that is necessary just because the subprogram is
overriding, or just because we need a controlling parameter for the
dispatch.
