[Bug libgcj/18266] SIGSEGV in GC_register_finalizer_inner ()

I've been looking into this a bit.

The current problem I see is that the heavyweight lock stuff
relies on the GC.  This won't interact well with the current
code in natReference.cc, as those data structures are not scanned.

Also, I do think that both calls to _Jv_RegisterFinalizer in
Reference::create are problematic.  The first call registers a finalizer
for the Reference, the second for the referent.  But, there is nothing
preventing a subclass of Reference from having a finalizer; or from
user code acquiring a heavy lock on a Reference object.  So, all
cases have to be handled here.
