* Idea: The set of chain tips is the active chain tip, plus orphan blocks which do not have another orphan building off of them.
* Algorithm:
* - Make one pass through BlockIndex(), picking out the orphan blocks, and also storing a set of the orphan block's pprev pointers.
* - Iterate through the orphan blocks. If the block isn't pointed to by another orphan, it is a chain tip.
* - add ::ChainActive().Tip()
* - Add the active chain tip
