What do the edge flags look like after cprop changes the jump?  EDGE_FALLTHRU
should be set.

Also, the unconditional JUMP_INSN should be removed.  Unconditional jumps are
removed when going into cfglayout mode, and when a conditional jump is turned
into  an unconditional jump, the whole JUMP_INSN can be removed.
