Robert Griesemer 5a3900b23c go/types, types2: implement alternative comparable semantics
This is an experiment to see the impact of a potential spec change:
As an exception to the rule that constraint satisfaction is the same
as interface implementation, if the flag Config.AltComparableSemantics
is set, an ordinary (non-type parameter) interface satisfies the
comparable constraint. (In go/types, the flag is not exported to
avoid changing the API.)

Disabled by default. Test files can set the flag by adding

// -altComparableSemantics

as the first line in the file.

For #52509.
