Toon, this cannot be right.

What is the right way to replace an accessor with a data property?

[Toon Verwaest, 2015/02/27 12:44:10]

This isn't right indeed. Are you sure you need this? it.PrepareForDataProperty()
should have reconfigured and reloaded the propertyinfo, so you should be in
state_ == DATA by the time you SetDataProperty.

   Handle<JSObject> holder = GetHolder<JSObject>();
   if (holder_map_->is_dictionary_map()) {
     NameDictionary* property_dictionary = holder->property_dictionary();
