Hi Tobi,
I would like to remove the SCEVRewriter code and replace it with a call to
SCEVAddRec::apply (see attached a patch that adds just this function). More
precisely I want to add another function called apply_map that applies a map
(loop -> expr) on a given scev. This is the apply function on a multi-variate
polynomial.
So here is an...

Other code would be able to call apply: it's a general operation that can be
