Allow anonymous value types to be constructed

Only anonymous object types are necessarily uncreatable. You don't need
a name in order to construct or populate a value type. Since we can now
construct QSize, QRect, and QPoint, the engine will try to construct
them from the 'F' variants where applicable. Allow this.
