Comment(by igloo):

 Hmm, OK. I was going to suggest a final renaming pass (in which only
 generated names get renamed) and ''not'' throwing the result away, so that
 it's easier to understand when the hash is or isn't changing.

 But I think that would be worse, because then the -ddump-simpl etc names
 wouldn't match the final names.

 So your !DeBruijn idea sounds best to me.
