Revert "[LoopVectorizer] Add support for chaining partial reductions (#120272)" (#124198) ...

Introduced stack buffer overflow, see #120272.

`getScaledReduction` can return empty vector, and there is not check for
that.

This reverts commit c9b7303b9b18129c4ee6b56aaa2a0a9f59be2d09.
This reverts commit caf0540b91b0fee31353dc7049ae836e0f814cff.
