  Log Message:
  -----------
  [VPlan] Consider non-header phis in planContainsAdditionalSimp.

Update planContainsAdditionalSimplifications to also check phis not in
the loop header. This ensures we don't miss cases where VPBlendRecipes
(which correspond to such phis) have been simplified.

Fixes https://github.com/llvm/llvm-project/issues/107473.
