We need to move this to JavaScriptBackend.registerCompileTimeConstantInternal
under a flag that the constant occurred in executed code (i.e. not in metadata).
It is needed to detect registration of custom elements.

-      // If the type is a web component, we need to ensure the constructors are
-      // available to 'upgrade' the native object.
-      TypeConstantValue type = constant;
-      Element element = type.representedType.element;
-      if (element != null && element.isClass) {
-        registry.registerTypeConstant(element);
-      }
-    }
-    push(backend.emitter.constantReference(constant));
-  }
-
   visitConstant(HConstant node) {
     assert(isGenerateAtUseSite(node));
-    generateConstant(node.constant);
-
+    push(backend.emitter.constantReference(node.constant));
     registry.registerCompileTimeConstant(node.constant);
     backend.constants.addCompileTimeConstantForEmission(node.constant);
   }
