[Checkers] TypesRelations loop

[Matt Papi]

Actually, it (or a similar problem) is still happening. Same commands,
etc. as above, but under SVN r2251:

        at checkers.util.TypeRelations.isSubtypeImpl(TypeRelations.java:171)
        at checkers.util.TypeRelations.compareTypeArg(TypeRelations.java:58)
        at checkers.util.TypeRelations.compareTypeArguments(TypeRelations.java:116)
