  Log Message:
  -----------
  [SLP]Use revectorized value for extracts from buildvector, beeing
vectorized.

If the insertelement instruction is vectorized, and the extractelement
instruction from such insertelement also vectorized as part of the same
tree, need to extract from the corresponding for insertelement vectorized value rather than original insertelement instruction.
