fix phisources during CBR-BR conversion
When a parent is removed from a BB containing one or several phi-nodes,
the corresponding phi-sources must be removed from the phi-node.
However this is not done and consequentially:
* it becomes impossibly to correctly reason about the flow of values
through these phi-nodes.
* simplifications are missed (e.g. if-conversion).
