       binary-search if-ladders.  It would be nice to be able to do that in

+      Add phi nodes to the CSE pass.

+    <task name="RemovePhi" mesa="no">
+      Implement a pass that removes pointless phi nodes.  After copy
+      propagation and other optimization passes happen, it's easy to end up
+      with phi nodes with all sources the same.  In this case, we can just
+      remove the phi node entirely and replace every use of its definition
+      with the common source.
