Good point, thanks.

I don't think that is enough though, because I don't think the BINFO
slots mean the same thing in g++ and gcj.

Anyway, I don't want to derail this conversation.  If we really want
to strength reduce interface dispatch to virtual dispatch in LTO then
we'll need to find some relatively language neutral way to express
that.
