ART: Fix RegisterNative order

First check for both direct and virtual methods in the current class,
then move to the parent.

Optimize registration by checking first whether the current method
under test is native. This slows down registering implementations
in parent classes. Add a CheckJNI warning for this.

Add a run-test to check the behavior. Fix host comparison testing.
