--- Comment #7 from Richard Biener <rguenth at gcc dot gnu.org> ---
Technically loop distribution would be one place to add this. Or SCEV cprop.
The pattern matching should be quite cheap - the question is of course how many
different ways to express popcount exist... so it does somewhat feel like a
SPEC hack...
