Ensure that the "creating default object from empty value" warning is always thrown. Previously some cases were missing the warning, in particular those going through FETCH_OBJ_W rather than a dedicated opcode (like ASSIGN_OBJ). One slightly unfortunate side-effect of this change is that something like $a->b->c = 'd' will now generate two warnings rather than one when $a is null (one for property b, one for property c).

Ensure by value assignments leave temporaries on the stack, for all sorts of assignees.
