This patch implement instruction reachability for AAFunctionReachability
attribute. It is used to tell if a certain instruction can reach a function
transitively.
NOTE: I created a new commit based of D106720 and set the author back to
Kuter. Other metadata, etc. is wrong. I also addressed the
remaining review comments and fixed the unit test.

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.

checkForAllInstructions was not handling declarations correctly.
It should have been returning false when it gets called on a declaration
The patch also fixes a test case for AAFunctionReachability for it to be able
to pass after the changes to the checkForAllinstructions.

This attribute uses Attributor's internal 'optimistic' call graph
information to answer queries about function call reachability.
Functions can become reachable over time as new call edges are
discovered.
