cfg: remove phi-nodes when merging BBs
When merging BBs, it's possible that the top BB feeds one or
several phi-nodes in the bottom BB. Since phi-nodes only make
sense for values incoming from the parent BBs, these phi-nodes
can and should be removed when merging the BBs.
So, when merging BBs, remove these related phi-nodes.
