	* doc/invoke.texi: Add documentation for the new option.
	* tree-dump.c: Move general dump file related functionality into
	dumpfile.c. Remove unneeded headers.
	* tree-dump.h: Move function declarations into dumpfile.h.
	* dumpfile.h: Include "line-map.h". Add defines for MSG flags.
	(struct dump_file_info): Move here from tree-dump.c.  Rename flags
	to pflags, state to pstate, stream to pstream, filename to
	pfilename. All callers updated. Add alt_flags, alt_state,
	alt_filenmae, alt_stream.
	* tree-vectorizer.c: Include "dumpfile.h". Remove vect_dump.
	(vect_set_dump_settings): Remove.
	(vect_print_dump_info): Ditto.
	* tree-vectorizer.h: Remove declaration of vect_dump and
	vect_print_dump_info.
	* tree-vect-loop.c: Include "dumpfile.h". Use new dump style.
	* tree-vect-data-refs.c: Ditto.
	* tree-vect-stmts.c: Ditto.
	* tree-vect-slp.c: Ditto.
	* tree-vect-patterns.c: Ditto.
	* tree-vect-loop-manip.c: Ditto.
	* testsuite/gcc.target/i386/vect-double-1.c: Fix test.
	* opts.c (vect_set_verbosity_level): Remove.
	(common_handle_option): Handle -fopt-info flag. Deprecate
	-ftree-vectorizer-verbose.
	* tree-parloops.c (gather_scalar_reductions): Remove reference to
	vect_dump.
	* flag-types.h: Remove vect_verbosity_levels.
	* common.opt: Add -fopt-info. Deprecate -ftree-vectorizer-verbose.
	* opts-global.c (dump_remap_tree_vectorizer_verbose): New
	function.
	(handle_common_deferred_options): Handle -fopt-info and
	-ftree-vectorizer-verbose.
	* Makefile.in: Add dumpfile.o.
	(tree-dump.o): Update dependencies.
	(tree-vect-loop.o): Ditto.
	(tree-vect-loop-manip.o): Ditto.
	(tree-vect-slp.o): Ditto.
	(tree-vect-stmts.o): Ditto.
	(tree-vectorizer.o): Ditto.
	(opts.o): Ditto.
	* passes.c (finish_optimization_passes): Instead of using
	dump_begin/dump_end, use dump_start/dump_finish. Do not use dump_file.
	(pass_init_dump_file): Ditto.
	* c-decl.c (c_write_global_declarations): Use a different method
	to determine if the dump has ben initialized.
	* decl2.c (cp_write_global_declarations): Use a different method
	to determine if the dump has ben initialized.
