Whitney Tsang 15b7f5b72d PHINode: introduce setIncomingValueForBlock() function, and use it. ...

Summary:
There is PHINode::getBasicBlockIndex() and PHINode::setIncomingValue()
but no function to replace incoming value for a specified BasicBlock*
predecessor.
Clearly, there are a lot of places that could use that functionality.
