  Log Message:
  -----------
  [SLP]Improve cost model for the shuffled extracts.

Improved the calculation of the shuffled extracts, where possible. Need
to calculate the cost for the extracted scalars if some users are not
insertelements + improved the total estimation of the shuffled scalars
used in insertelements build vectors.
