  Log Message:
  -----------
  [SLP]Introduce shuffle of the nodes + gather/vectorbuild  of the remaining scalars.

Currently compiler does not support mixing of shuffled nodes
+ gather/buildvector of the remaining scalar values. It may reduce total
  number of instructions and improve performance of the
  gather/buildvector sequences.
