+        continue;
+    } else if (isa<SCEVAddRecExpr>(RightSCEV))
+      continue;
----------------
Why do we bail if both left and right are AddRecs? What is the problem?

If there are no conceptual troubles with handling this case, I'd rather handle it. And if so, please add a corresponding test.
