452 (c_finish_omp_clauses): Drop generic_field_head, structure
453 elements are now always mapped even as array section bases,
454 diagnose same var in data sharing and mapping clauses. Diagnose if
455 linear step on declare simd is neither a constant nor a uniform
456 parameter. Look through POINTER_PLUS_EXPR for array section
457 reductions. Diagnose the same var or function appearing multiple
458 times on the same directive. Fix up wording for the to clause if t
459 is neither a FUNCTION_DECL nor a VAR_DECL. Diagnose nonmonotonic
460 modifier on kinds other than dynamic or guided or nonmonotonic
461 modifier together with ordered clause.
