I'm not sure what Geoff was trying to accomplish with this change,
but it's wrong.

'gcc -da nothing.c' crashed because execute_todo does:

      if (properties & PROP_trees)
        dump_function_to_file (current_function_decl,
                               dump_file, dump_flags);
      else if (properties & PROP_cfg)
        print_rtl_with_bb (dump_file, get_insns ());
      else
        print_rtl (dump_file, get_insns ());

and get_insns() is not available yet, we do not have RTL.

        * tree-cfg.c (pass_remove_useless): Revert last change.
        * tree-optimize.c (init_tree_optimization_passes): Initialize
        all_lowering_passes with PROP_gimple_any.
