[Bug libgcj/15001] Using JNI with interpreter and interface methods yields SIGSEGV

meth->index for an interface method should contain the IDT dispatch index for
that method, which allows us to use fast interface dispatch
(_Jv_LookupInterfaceMethodIdx) for Method.invoke() calls. Unfortunately, this
index is useless without also knowing which interface the method belongs to, and
as Tom points out, we do not currently have a way to get from a JNI jMethodID to
the interface, hence this PR.

Perhaps a special flag for interface methods would be the best fix in the short
term, until we can somehow fix JNI to give us a class/interface from a jMethodID.
