:) Lovely
After all I needed to fix only two bugs to get LO build with mainline LTO again.

Anyway those are warning I currently get with ODR type merging.  The first three are
quite puzzling - the type layout differs, but by abstract field so I am unable to print
out any resonable message. This may suggest difference in virtual inheritance or someting like
that (or just plain bug in my code comparing types).  I will dig deeper into it tomorrow.

Most of the later cases seems real.
