Thanks - that was the start of what I requested, but not complete. I've added the test here using auto-generated CHECK lines that show baseline (without this patch) results:
rGdf79443 <https://reviews.llvm.org/rGdf794431e0a36d7d4fda685710714e913277f22f>

Please rebase and update that file using the script at llvm/utils/update_test_checks.py.
I don't think we need to duplicate the test in the SLP folder now that we have coverage for this example in PhaseOrdering, but if you think that is still useful, that can be added independently of this patch.
