tree: gc crash due to dummy object.
* tree.c (tr_rebuild): The dummy on-stack node we use in the rebuilding
process must have its generation field set to 1 rather than 0, so it looks
like a mature heap object rather than a baby object. Otherwise
when its pointer is assigned to another node which happens to
be gen 1, the on-stack dummy will be added to the checkobj array,
and gc will try to mark it.
