2017-10-04Fix UAF in SetVisible().Henrique Nakashima
SetVisible() may be called during Destroy() which may be called during SetVisible(). This fixes the latest in a family of bugs that happen after an instance is freed by code triggered by JS code while it's executing a method. The CL has a lot of protection for many of these points where JS may be executed and potentially destroy objects. The return types of many methods that may execute JS have been changed to bool, indicating whether the instance is still alive after the call.
