--- Comment #7 from Sanjay Patel <spatel+llvm at rotateright.com> ---
Should be fixed with:
https://reviews.llvm.org/rL312379

If horizontal ops are expected to be generated in ways other than this exact
example, I suspect we can still miss those optimizations. 

Ie, if we really care about horizontal ops, we should get a bigger picture of
the uses, so we can properly fix the problem.
