D89489 <https://reviews.llvm.org/D89489> added some logic to the interleaved access pass to attempt to undo the folding of shuffles into binops, that instcombine performs. If early-cse is run too, the binops may be commoned into a single operation with multiple shuffle uses. It is still profitable reverse the transform though, so long as all the uses are shuffles.
