I think we've talked about enhancing the pattern recognizer to expand it as
mult at the tree level, reusing parts of the expander code for that. I believe
I've looked at it, but can't find any patch (I think it was around mid December
when
sdivmod pattern recognizer has been added). I'll look at it again.
