This is not enough, on HEAD you end up with *.vcg files only containing
} and newline.

But if print_rtl_with_bb should be run from execute_todo rather than
execute_one_pass, here is the patch that does the job for me.
I have noticed GCC 4.0 code being pretty different, so I have prepared
a separate 4.0 version as well.

On 4.0 branch, clean_graph_dump_file is called by close_dump_file,
so it is both superfluous to call it also in execute_one_pass and
additionally calling it there also introduces the ICE.
