Hi,

While I'm still at the bugs' chapter, here is a long due patch for this
missed optimization PR.  We just make use of the info that scev
provides and the magic happens.

I'm bootstrapping and testing the attached patch on i686-linux,
okay for trunk once it finishes?

This is ok for mainline.

Thanks,
Richard.
