--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
There's also association coming into play.  I wonder if it makes more sense to
keep the shift insns together (allow all constants) and instead lower/split
them with a LCM algorithm that can maximize re-use and optimize code placement
(at the expense of register use - not sure how bad that is).
