Not sure where the failure is. They _seem_ to be related to Andrew's changes, but I haven't actually checked. They are codegen failures.

Yes these are all caused by my change, I am trying to figure out how to fix them
and how I did not see them in my testing.

I still don't understand why this patch works but it is most likely a bug
some in the C++ front-end somewhere from in setting up the inheritance field
decls. I don't have time to track down why they are not working correctly
so I decided to put a FIXME and a check for if the field is an artificial field

OK? Tested on powerpc-apple-darwin, this time with no regressions and it fixes
the regressions that were caused by my first patch.
