--- Comment #3 from Jan Hubicka <hubicka at ucw dot cz> ---
OK, I now recall. The intend was really to have three values 
- profile before pass was run (which you can see from stats of previous
  pass)
- profile after pass was run
- profile after cleanups

This is somewhat useful because, say for CCP one can see how much code
sped up just by removing some calculation and how much it was affected
by subsequent unreacable code removal.  If we can't calculate the middle
value safely, we can just drop it.
