New version that fixes the problem with base classes not appearing in order of increasing offset.

This issue was discovered in the multistage build, but the test case has now been extended for this situation.

Also changed to obtain the the size of the base subobject with `getDataSize()` since other subobjects may be allocated in its tail padding.
