Add assertions for the initialization of the cycle collector's Edge
A common mistake when changing how the CC graph built, at least for me, is to forget to set the first or last child of a node. This results in null pointer crashes in weird places. It is easier to diagnose these problems if we check any time the EdgePool::Iterator is touched that it is initialized. I'm going to put these behind a special #define because this is not a very useful check unless you are altering how the graph is built. These kinds of mistakes will result in crashing even without the assertions, the assertions just make them easier to diagnose. I personally only find it useful once or twice a year.
