invoke.texi: Remove -dv documentation.

gcc/
	* doc/invoke.texi: Remove -dv documentation.  Fix up graph dump related
	documentation.  Document the '-graph' dump option.  Complete the '-slim'
	dump option documentation.

	* common.opt (Variable graph_dump_format): Remove.
	* flag-types.h (enum graph_dump_types): Remove.
	* flags.h (dump_for_graph): Remove.
	* opts.c (decode_d_option): Remove -dv handling.
	* sched-int.h (print_insn, print_pattern, print_value): Move prototypes
	from here ...
	* rtl.h: ...to here.  Add note that these functions ought to be in
	another file.
	* sched-vis.c (print_insn): Add detailed dump for insn notes.
	* print-rtl.c (dump_for_graph): Remove.
	(print_rtx): Remove dump_for_graph related code.
	* graph.c: Almost complete re-write to dump DOT (GraphViz) dumps
	instead of VCG dumps.
	* graph.h (print_rtl_graph_with_bb): Update prototype.
	* passes.c (finish_optimization_passes): Fix profile dump finishing.
	Unconditionally loop over graph dumps to finalize.
	(execute_function_dump): Split code to dump graphs to separate block.
	(execute_one_pass): Don't set TDF_GRAPH here, let the dump option
	decoders do their job.

	* ddg.c (vcg_print_ddg): Make it a DEBUG_FUNCTION.
	* toplev.c: Don't include graph.h.
	* tree-optimize.c: Don't include graph.h.

testsuite/
	* testsuite/gcc.dg/20050811-1.c: Change -dv option to -graph option
	to -fdump-rtl-all.
	* testsuite/gcc.dg/pr37858.c: Remove -dv option.
