I've always said: Use LTO at your own risk.  It has been broken for
months at a time because I simply do not have time to give it the TLC
it needs.  I expect that devirtualisation capabilities to be a little
more limiting than advertised by GCC, as you do not get these sorts of
optimisations for free (may need some extra support from respective
frontends).
