[issue11628] cmp_to_key generated class should use __slots__

[Éric Araujo]

Éric Araujo <merwok at netwok.org> added the comment:

Right, I edited the versions field to match the versions that contain cmp_to_key, but if this behavior change is just for performance, it’s not a candidate for backport.

Chris: I’d go with the simpler implementation.
