removeIncomingValue - Remove an incoming value.
This is useful if a predecessor basic block is deleted. The value removed is returned.
If the last incoming value for a PHI node is removed (and DeletePHIIfEmpty is true), the PHI node is destroyed and any uses of it are replaced with dummy values. The only time there should be zero incoming values to a PHI node is when the block is dead, so this strategy is sound.
