Gcj does try to optimize the generation of Jv_InstanceOf but doesn't
try to do this particular optimization. For this particular test case,
gcj now decides that the answer should be `false' (in the past, it
would issue a call Jv_IsInstanceOf.) So yes, there's something
wrong. I'll look into it shortly. The branch is affected too.
