* dumpfile.h (enum tree_dump_index): Remove TDI_vcg.

	* dumpfile.c (dump_files[]): Remove entry for TDI_vcg.
	* tree-cfg.c (gimple_cfg2vcg): Remove.
	(build_gimple_cfg): Don't call it.
	* doc/invoke.texi (-fdump-tree-vcg): Remove documentation.
	Correct GraphViz documentation, it does handle multiple functions
	in a single dump.
