  Log Message:
  -----------
  [SLP]No need to schedule/check parent for extract{element/value} instruction.

The instruction extractelement/extractvalue are not required to
be scheduled since they only depend on the source vector/aggregate (with
constant indices), smae applies to the parent basic block checks.
Improves compile time and saves scheduling budget.
