  -----------
  [SLP]Try to vectorize small graph with extractelements, used in buildvector.

If the graph incudes only single "gather" node with only
extractelements/undefs, which used only in insertelement-based
buildvector sequences, it still might be profitable to vectorize it.
Need to rely on the cost model, not throw this graph away immediately.
