When a member in the interface of a non-abstract class is found to
have an implementation with the correct name which does not override
the representative declaration of the member in the interface (and thus
has not been checked against that member for override validity), call
the override check to check interface validity.
Override relations thus checked produce an extra context message
explaining that the override relation must hold because both members
are inherited by a non-abstract class.
