  Log Message:
  -----------
  [VPlan] Include wide IVs with NUW as monotonic in verifier. (#194959)

This fixes a verifier failure after
https://github.com/llvm/llvm-project/pull/194267 due to a wide IV 
used in header mask compare being narrowed during later 
optimizations.

This is in line how we treat other recipes, like adds, in the verifier
check.

Should fix https://lab.llvm.org/buildbot/#/builders/187/builds/19595.
