[PATCH] D27674: [StaticAnalysis] Remove unnecessary parameter in CallGraphNode::addCallee.

[Haojian Wu via Phabricator via cfe-commits]

Remove the CallGraph in addCallee as it is not used in addCallee.
It decouples addCallee from CallGraph, so that we can use CallGraphNode
within our customized CallGraph.
