GCC versions up to 2.8.x did not have any notion of a CFG at -O0. They
worked all the time with jumps directly encoded in their intermediate
representation.
Yes, this is bad. Luckily more and more passes in GCC have been
converted to look directly at CFG edges, but not all of GCC does even
now, after 10+ years.
