Please review this change (initial patch provided by David Holmes; I
rearranged it a little and added more comments).
We reinitialize the markWord of all archived objects to remove any side
effect of GC/locking/etc during "java -Xshare:dump".
(David mentioned in the bug comments about assertions inside the
identity_hash() call, but maybe this should be fixed in a different bug?)
Tested with mach5 tiers 1-4.
