+    tree-optimization/111294 - better DCE after forwprop
+    
+    The following adds more aggressive DCE to forwprop to clean up dead
+    stmts when folding a stmt leaves some operands unused.  The patch
+    uses simple_dce_from_worklist for this purpose, queueing original
+    operands before substitution and folding, but only if we folded the
+    stmt.
