Don't access QObjectPrivate::declarativeData unguarded
The QObjectPrivate::declarativeData member is stored in a union with currentChildBeingDeleted. The QObject destructor always sets the currentChildBeingDeleted member of the union. It also sets the isDeletingChildren bool, which is the only way to find out which union member we can safely access. While the QObject destructor is deleting children and isDeletingChildren is set, we must not access the declarativeData member of the union. Add a test case that initializes the function pointers for the declarative handlers and constructs a situation where an object emits a signal while it is destroying children.
