where base object bridge-type does not match method bridge-type.

Reviewed by Alexey Proskuryakov.

The code assumes users will only attempt to invoke a Java method
on a Java base object, etc.
Add language specific subclasses of RuntimeMethod, and pass the
RuntimeMethod into invokeMethod, so we can typecheck before
casting.  Throw an exception on type mismatch.
