Add some investigation code for dumping additional info when
MarkedBlock::Handle is invalid

Reviewed by Mark Lam and Keith Miller.
We want to dump additional information when this failure case is hit to
understand why this
could be taking place.
This patch is an updated version of Yijia's patch, which implemented most of
the logging.
