2865 reductions. Diagnose the same var or function appearing multiple
2866 times on the same directive. Fix up wording for the to clause if t
2867 is neither a FUNCTION_DECL nor a VAR_DECL. Diagnose nonmonotonic
2868 modifier on kinds other than dynamic or guided or nonmonotonic
2869 modifier together with ordered clause.
