  Log Message:
  -----------
  [Scalarizer] Ensure valid VectorSplits for each struct element in `visitExtractValueInst` (#128538)

Fixes #127739 

The `visitExtractValueInst` is missing a check that was present in
`splitCall` / `visitCallInst`.
This check ensures that each struct element has a VectorSplit, and that
each VectorSplit contains the same number of elements packed per
fragment.
