This patch moves the following things to being GC-allocated: - Bindings::CallbackType - HTML::EventHandler - DOM::IDLEventListener - DOM::DOMEventListener - DOM::NodeFilter Note that we only use PlatformObject for things that might be exposed to web content. Anything that is only used internally inherits directly from JS::Cell instead, making them a bit more lightweight.
