Chandler Carruth 4d480e7c41 [LCG] Add a unittest for the LazyCallGraph. I had a weak moment and ... resisted this for too long. Just with the basic testing here I was able to exercise the analysis in more detail and sift out both type signature bugs in the API and a bug in the DFS numbering. All of these are fixed here as well. The unittests will be much more important for the mutation support where it is necessary to craft minimal mutations and then inspect the state of the graph. There is just no way to do that with a standard FileCheck test. However, unittesting these kinds of analyses is really quite easy, especially as they're designed with the new pass manager where there is essentially no infrastructure required to rig up the core logic and exercise it at an API level. As a minor aside about the DFS numbering bug, the DFS numbering used in LCG is a bit unusual. Rather than numbering from 0, we number from 1, and use 0 as the sentinel "unvisited" state. Other implementations often use '-1' for this, but I find it easier to deal with 0 and it shouldn't make any real difference provided someone doesn't write silly bugs like forgetting to actually initialize the DFS numbering.
