* tree-phinodes.c (reserve_phi_args_for_new_edge, remove_phi_node):

	Use phi_nodes_ptr.
	(create_phi_node): Use set_phi_nodes.
	* omp-low.c (expand_omp_parallel): Use bb_stmt_list.
	* tree-if-conv.c (process_phi_nodes): Use set_phi_nodes.
	(combine_blocks):  Use bb_stmt_list and set_bb_stmt_list.
	* tree-flow-inline.h (phi_nodes, set_phi_nodes,
	(bsi_start, bsi_last): Use bb_stmt_list.
	(phi_nodes_ptr, bb_stmt_list, set_bb_stmt_list): New functions.
	* cfgexpand.c (expand_gimple_basic_block): Use bb_stmt_list.
	Traverse the statements using tsi iterator.
	* basic-block.h (struct basic_block_def): Fields stmt_list
	and phi_nodes moved to ...
	(struct tree_bb_info): ... new structure.
	* tree-cfg.c (create_bb): Allocate il.tree.  Use set_bb_stmt_list.
	(tree_merge_blocks): Use bb_stmt_list and set_bb_stmt_list.
	(remove_bb): Handle blocks with NULL stmt list.  Clear il.tree field.
	(tree_verify_flow_info): Verify that il.tree is not set for
	entry and exit block.
	(tree_split_block): Use set_bb_stmt_list.
