Eliminate label_to_block_map macro.

gcc/
	* basic-block.h (label_to_block_map): Eliminate macro.

	* gimple.c (gimple_set_bb): Replace uses of label_to_block_map
	with uses of label_to_block_map_for_fn, making uses of cfun be
	explicit.
	* tree-cfg.c (delete_tree_cfg_annotations): Likewise.
	(verify_gimple_label): Likewise.
