cmd/compile: add support for alternative comparable semantics
Add the experimental compiler flag -altcomparable. If set, the
compiler uses alternative comparable semantics: any ordinary
(non-type parameter) interface implements the comparable
constraint.
This permits experimenting with this alternative semantics
akin to what is proposed in #52509.
For #52509.
