  Log Message:
  -----------
  [Attributor] AAFunctionReachability, Handle CallBase Reachability.

This patch makes it possible to query callbase reachability
(Can a callbase reach a function Fn transitively).
The patch moves the reachability query handling logic to a member class,
this class will have more users within the AA once we add other function
reachability queries.
