  Log Message:
  -----------
  [VPlan] Remove dead exit block handling code in HCFGBuilder.

The mapping of IR ExitBB to a VPBB isn't used. It also sets an incorrect
VPBB for the ExitBB; the regions successor is the middle block, no the
exit block.

It also unnecessarily triggers an assertion after 38376dee922.
