54bb64cfb2 freeze sites for dead values in resolveOriginalSites 
Previously, we simply removed the element from the sites array, but
this led to problems when the junction sites are shared among multiple
junctions such that the value at a given index is live at one junction
and dead at another.

3787985b25 implement basic finalization support 
This implementation does not conform to the Java standard in that
finalize methods are called from whichever thread happens to be garbage
collecting, and that thread may hold locks, whereas the standard
guarantees that finalize will be run from a thread which holds no locks.
Also, an object will never be finalized more than once, even if its
finalize method "rescues" (i.e. makes reachable) the object such that it
might become unreachable a second time and thus a candidate for
finalization once more.  It's not clear to me from the standard if this
is OK or not.

Nonwithstanding the above, this implementation is useful for "normal"
finalize methods which simply release resources associated with an
object.

47ab980550 fix thread heap overflow corner case in allocate3 
The previous code relied on the invalid assumption that the thread-local
heaps for all threads would have been cleared immediately following a
garbage collection.  However, the last thing the garbage collection
function does is run finalizers which may allocate new objects.  This
can lead allocate3 to call allocateSmall with a size which is too large
to accomodate, overflowing the heap.

The solution is to iterate until there really is enough room for the
original allocation request.
