--- Comment #11 from kugan at gcc dot gnu.org ---
In remove_unreachable_nodes, just before ipa-cp, this node becomes local
(address taken is false and local.local = true). After that, when
ipa_propagate_frequency is run, which updates the frequency to zero. I think we
should check the frequency at this point in time and remove such nodes.
