Ok, so parking this, and instead focus on reigning in vectorisation? I guess it makes sense and is another way of doing it.
I can't remember why we went for fixing the codegen. Perhaps that was just a fun exercise, and avoids looking at cost-modelling again if we manage to get the vector code on par with the scalar code (that would be good enough for this case).
