	are used in acc parallel reductions.
	(lower_rec_input_clauses): Remove dead code.
	(lower_oacc_reductions): Add support for reference reductions.
	(lower_reduction_clauses): Remove dead code.
	(lower_omp_target): Don't remap variables appearing in acc parallel
	reductions.
	* tree.h (OMP_CLAUSE_MAP_IN_REDUCTION): New macro.
