LGTM.

For reference, the bug was introduced with e239198cdbbf <https://reviews.llvm.org/rGe239198cdbbf2689ffe2c21ea8feab5b7a4a8a02>. Before that patch, the pattern would get reduced in multiple steps using demanded elements, so there's no difference in optimization on this kind of shuffle pattern AFAICT.
