I pushed out my current one.
It keeps the old semantics wrt the clamp() static_assert, and it
obviously has the "allow small unsigned types to promote to 'int'"
that I already did earlier.
I still suspect we shouldn't do that relaxed integer promotion rule,
but it's what we used to do, and it's easy to get rid of if we decide
to, and it's a separate issue from the whole "make minmax expansion
more reasonable".
