* cfgloopmanip.c (remove_path, loopify, duplicate_loop_to_header_edge):

	Change dom_bbs to vector.  Add argument to iterate_fix_dominators call.
	* loop-unroll.c (unroll_loop_runtime_iterations): Ditto.
	* tree-cfg.c (tree_duplicate_sese_region): Change doms to vector.
	Add argument to iterate_fix_dominators call.
	(remove_edge_and_dominated_blocks): Pass vector to bbs_to_fix_dom.
	* gcse.c (hoist_code): Change domby to vector.
	* cfghooks.c (make_forwarder_block): Change doms_to_fix to vector.
	Add argument to iterate_fix_dominators call.
	* loop-doloop.c (doloop_modify): Changed recount_dominator to
	recompute_dominator.
	* lambda-code.c (perfect_nestify): Ditto.
	* cfgloopanal.c: Include graphds.h.
	(struct edge, struct vertex, struct graph, dump_graph, new_graph,
	add_edge, dfs, for_each_edge, free_graph): Moved to graphds.c.
	(mark_irreducible_loops): Use graphds_scc.  Remove argument from
	add_edge call.
	* graphds.c: New file.
	* graphds.h: New file.
	* dominance.c: Include vecprim.h, pointer-set.h and graphds.h.
	(get_dominated_by, get_dominated_by_region): Change return type to
	vector.
	(verify_dominators): Recompute all dominators and compare the results.
	(recount_dominator): Renamed to ...
	(recompute_dominator): ... this.  Do not check that the block is
	dominated by entry.
	(iterate_fix_dominators): Reimplemented.
	(prune_bbs_to_update_dominators, root_of_dom_tree,
	determine_dominators_for_sons): New functions.
	* et-forest.c (et_root): New function.
	* et-forest.h (et_root): Declare.
	* Makefile.in (graphds.o): Add.
	(cfgloopanal.o): Add graphds.h dependency.
	(dominance.o): Add graphds.h, vecprim.h and pointer-set.h dependency.
	* basic-block.h (get_dominated_by, get_dominated_by_region,
	iterate_fix_dominators): Declaration changed.
	(recount_dominator): Renamed to ...
	(recompute_dominator): ... this.
	* tree-ssa-threadupdate.c (thread_block): Free dominance info.
	(thread_through_all_blocks): Do not free dominance info.
