Comment (by dfeuer):

 I'm working on the separate optimization level tracking. I'll probably
 have that done by the end of the day. I'll likely need a bit of help to
 get the user interface sorted. I'm not sure how that should look. Maybe a
 separate `-frecompile-for-opt-level-change`? By the way, as far as I can
 tell, we ''don't'' track changes in ''individual'' optimization flags,
 like `-ffull-laziness`. I imagine we should do something about that.
