  -----------
  [LV] Increase max VF if vectorized function variants exist (#66639)

If there are function calls in the candidate loop and we have vectorized
variants available, try some wider VFs in case the conservative initial
maximum based on the widest types in the loop won't actually allow us
to make use of those function variants.
