  Log Message:
  -----------
  Revert "[SLP]Do not emit extract elements for insertelements users, replace with shuffles directly."

This reverts commit fc9c59c355cb255446e571b4515b5e41a76503c4.

The patch triggers an assertion when building SPEC on X86. Reduced
reproducer shared at D107966.

Also reverts follow-up commit 11a09af76d11ad5a9f1f95b561112af17ff81f80.
