We still use the object_value_of field of the native context in Crankshaft, so
you need to save the result of this there, i.e.

Handle<JSFunction> object_value_of = ...;
native_context()->set_object_value_of(*object_value_of);

Done.

     SimpleInstallFunction(isolate->initial_object_prototype(),
                           "__defineGetter__", Builtins::kObjectDefineGetter, 2,
                           true);
