  Log Message:
  -----------
  [SLP]Gather scalarized calls

If the calls won't be vectorized, but will be scalarized after
vectorization, they should be build as buildvector nodes, not vector
nodes. Vectorization of such calls leads to incorrect cost estimation,
does not allow to calculate correctly spills costs.
