  Log Message:
  -----------
  [VPlan] Account for canonical IV being simplified in verifier. (#203403)

In plain CFG plans, VPCurrentIterationPHIRecipe may be the first recipe,
if the canonical IV phi has been removed because it became unused (e.g.
the vector loop is known to only execute a single iteration).

Fixes https://lab.llvm.org/buildbot/#/builders/187/builds/20801.
