LibJS+js+test-js: Add GC debug mode that keeps cells "alive" as zombies
This patch adds a `-z` option to js and test-js. When run in this mode, garbage cells are never actually destroyed. We instead keep them around in a special zombie state. This allows us to validate that zombies don't get marked in future GC scans (since there were not supposed to be any more references!) :^) Cells get notified when they become a zombie (via did_become_zombie()) and this is used by WeakContainer cells to deregister themselves from the heap.
