  -----------
  [VectorCombine] Add test showing issue when running VectorCombine early.

Running -vector-combine early can introduce new vector operations,
blocking loop/SLP vectorization. The added test case could be better
optimized by the SLPVectorizer if no new vector operations are added
early.
