[PATCH] D118376: [x86] try harder to scalarize a vector load with extracted integer op uses

[Sanjay Patel via Phabricator via llvm-commits]

Patch updated:

1. Use `makeEquivalentMemoryOrdering` (see D119549 <https://reviews.llvm.org/D119549> for a similar change to the DAGCombiner code)
2. Added a regression test based on https://github.com/llvm/llvm-project/issues/53695 (with the old version of this patch, this test will fail).
