--- Comment #37 from Jeffrey A. Law <law at redhat dot com> ---
Another thought for dealing with this BZ:  Use the infrastructure Alex built to
identify blocks that are in effect forwarders (ie, they need not be copied for
jump threading).  Use that knowledge to thread deeper in the CFG each
iteration.
