The cehck for vptr could be done differently (is this class dynamic and its base class non-dynamic), and if we change the layout (to put the vptr after any base) then this code will break (could add an assertion that the vptr isn't present apart from at the start of the field list if that'd seem worthwhile). There's still later issues with lowering (if this patch causes crashes in lowering, do they result in fuzz failures/need to be avoided before this change is submitted?)
