I think these are not needed given my previous comments.

  public:
-  explicit LCheckMaps(LOperand* value) {
-    inputs_[0] = value;
+  explicit LCheckMaps(LOperand* context,
+                      LOperand* value) {

+    inputs_[1] = value;
   }

+  LOperand* context() { return inputs_[0]; }
+  LOperand* value() { return inputs_[1]; }
