Interface dispatch bug

Interface methods should bind to the lowest sub-interface. Only search
declared methods in a class before trying to find the interface method
via the iftables.

Unit test that declares toString in an concrete class, where toString
has been made an interface method in CharSequence. ecj compiles this
method call into an invokeinterface (hence the custom build).
