Support directly invoking interface default methods

With the Java 8 Language one is allowed to directly call default
interface methods of interfaces one (directly) implements through the
use of the super keyword. We support this behavior through the
invoke-super opcode with the target being an interface.

We add 3 tests for this behavior.

Currently only supports slow-path interpreter.

Invoke-super is currently extremely slow.
