* Add different types of GraphNodeInfos.
This adds support for multiple graph node infos.
It removes the assumption that information of
a graph node must be some strings and an offset.
* Increase buffer for printing graph node body
* Don't hardcode maximum label size
* Add graph node info for icfg
* Add node type info to CFG.
* Access address members properly for iCFG and CFG nodes
* Update test. Function names are no longer saved.
* Fix reachable double free of label
* Split graph node type from its sub-type to make it less confusing.
* Add integration tests for iCFG nodes.
* Fix, add mising buffer read
* Recognize more calls
* Add test for iCFG generation and its node details.
