Optimize CfgBuilder.BuilderVisitor.addNode().

Instead of keeping one list with the current exits, this fix makes the
exits tabulated by their "reason." This saves us unnecessary work in
addNode() since we don't have to iterate through all the exits at every
calls anymore.

For large modules, this gives a significant speedup.
