  -----------
  Revert "[SLP]Initial non-power-of-2 support (but still whole register) for reductions"

This reverts commit 7f2e937469a8cec3fe977bf41ad2dfb9b4ce648a as it causes
regressions in the tests it modifies, and undoes what was added in #100653
(which itself was a fix for a previous regression).
