tree.h (OMP_CLAUSE_FIRSTPRIVATE_NO_REFERENCE): Define.

gcc/
	* tree.h (OMP_CLAUSE_FIRSTPRIVATE_NO_REFERENCE): Define.
	* gimplify.c (gimplify_omp_for): Handle C++ range for loops with
	NULL TREE_PURPOSE in OMP_FOR_ORIG_DECLS.  Firstprivatize
	__for_end and __for_range temporaries on OMP_PARALLEL for
	distribute parallel for{, simd}.
	* omp-low.c (lower_rec_input_clauses): Handle
	OMP_CLAUSE_FIRSTPRIVATE_NO_REFERENCE on OMP_CLAUSE_FIRSTPRIVATE
	clauses.
gcc/c-family/
	* c-omp.c (c_omp_check_loop_iv_r): Look for orig decl of C++
	range for loops too.
gcc/cp/
	* cp-tree.h (cp_convert_omp_range_for, cp_finish_omp_range_for,
	finish_omp_for_block): Declare.
	* parser.c (cp_parser_for): Pass false as new is_omp argument to
	cp_parser_range_for.
	(cp_parser_range_for): Add is_omp argument, return before finalizing
	if it is true.
	(cp_convert_omp_range_for, cp_finish_omp_range_for): New functions.
	(cp_parser_omp_for_loop): Parse C++11 range for loops among omp
	loops.
	(cp_parser_omp_simd, cp_parser_omp_for, cp_parser_omp_distribute,
	cp_parser_omp_taskloop): Call keep_next_level before
	begin_omp_structured_block and call finish_omp_for_block on
	finish_omp_structured_block result.
	* semantics.c (handle_omp_for_class_iterator): Don't create a new
	TREE_LIST if one has been created already for range for, just fill
	TREE_PURPOSE and TREE_VALUE.
	(finish_omp_for): Don't check cond/incr if cond is global_namespace.
	Pass to c_omp_check_loop_iv_exprs orig_declv if non-NULL.  Don't
	use IS_EMPTY_STMT on NULL pre_body.
	(finish_omp_for_block): New function.
	* pt.c (tsubst_decomp_names): Add forward declaration.
	(tsubst_omp_for_iterator): Change orig_declv into a reference.
	Handle range for loops.  Move orig_declv handling after declv/initv
	handling.
	(tsubst_expr): Call keep_next_level before begin_omp_structured_block.
	Call cp_finish_omp_range_for for range for loops and use
	{begin,finish}_omp_structured_block instead of {push,pop}_stmt_list
	if there are any range for loops.  Call finish_omp_for_block on
	finish_omp_structured_block result.
	(dependent_omp_for_p): Always return true for range for loops if
	processing_template_decl.
