domwalk.c (walk_dominator_tree, [...]): Use VEC instead of VARRAY.

	* domwalk.c (walk_dominator_tree, init_walk_dominator_tree,
	fini_walk_dominator_tree): Use VEC instead of VARRAY.
	* domwalk.h (dom_walk_data): Change the type of

	* tree-ssa-dse.c (dse_initialize_block_local_data,
	dse_optimize_stmt, dse_record_phis, dse_finalize_block): Use
	VEC instead of VARRAY.
