I have patch in way for type & virtual tables ODR checking (the problem is that
it requires us to stream mangled type names to establish ODR equivalency at
link time. This adds extra 2% of streaming that I need to justify).  Current
mainline (I used for my test) reports ODR violation only for types with virtual
tables.  I will check if I notice more and will try to run it with full ODR
checking enabled.

I also want to add a way to dump the translation unit, because often these are
caused by different #defines or by -funsigned-char/-fsigned-char differences.
In those cases the erros output are quite puzzling ;)
