	(c_parser_omp_var_list_parens): Add ALLOW_DEREF optional parameter.
	Pass to c_parser_omp_variable_list.
	(c_parser_oacc_data_clause): Support attach and detach clauses.  Update
	call to c_parser_omp_variable_list.
	(c_parser_oacc_all_clauses): Support attach and detach clauses.
	(OACC_DATA_CLAUSE_MASK, OACC_ENTER_DATA_CLAUSE_MASK,
	OACC_KERNELS_CLAUSE_MASK, OACC_PARALLEL_CLAUSE_MASK,

	Update call to cp_parser_omp_var_list_no_open.
	(cp_parser_oacc_all_clauses): Support attach and detach.
	(OACC_DATA_CLAUSE_MASK, OACC_ENTER_DATA_CLAUSE_MASK,
	OACC_KERNELS_CLAUSE_MASK, OACC_PARALLEL_CLAUSE_MASK,
	OACC_SERIAL_CLAUSE_MASK): Add PRAGMA_OACC_CLAUSE_ATTACH.
	(OACC_EXIT_DATA_CLAUSE_MASK): Add PRAGMA_OACC_CLAUSE_DETACH.
	* semantics.c (handle_omp_array_sections_1): Reject subarrays for
	attach and detach.
	(handle_omp_array_sections): Use GOMP_MAP_ATTACH_DETACH instead of
	GOMP_MAP_ALWAYS_POINTER for OpenACC.
