The basic issue is that when we create the Phi node in the merge block, we need to set up the block/value pairs that indicate how the Phi will work. Importantly, the Phi -node expects to have an extry for each predecessor of the block in the CFG. Why +node expects to have an entry for each predecessor of the block in the CFG.
