	Unify the management of RTL and tree-level dump files.

	* cfgexpand.c (tree_expand_cfg): Fix incorrect comment.
	Don't print function name to the dump file, the pass manager
	would do this for us. Add code from the top of
	rest_of_compilation, up to the initial RTL dump.
	* passes.c (rest_of_handle_jump): Call fixup_tail_calls and
	close the DFI_sibling dump file.
	(rest_of_compilation): Don't do that here.  Remove code up to the
	initial RTL dump.
	(init_optimization_passes): Remove.
	(pass_rest_of_compilation): Change pass name to NULL.
	* toplev.c (lang_dependent_init): Do not use an empty dump file prefix.
	Do not call init_optimization_passes.
	* toplev.h (init_optimization_passes): Remove.

	* graph.c (print_rtl_graph_with_bb, clean_graph_dump_file,
	finish_graph_dump_file): Remove SUFFIX parameter.
