[cxx-abi-dev] Ordering of introduced functions before replicated overridden functions from non-primary

I'm not sure what you're getting at with these first two points; these
don't matter as far as I can tell.

Yes, this is a change.  GCC 3.2 is correct.  After laying out the
primary part of the vtable, you iterate through the remaining functions,
adding those that are overridden in the final derived class but do not
already appear.

The bullets in Category 2 are not supposed to indicate ordering,
although just yesterday another person was confused by this as well.

I will endeavor to clarify this portion.
