  [Attributor] Introduce AAGlobalValueInfo to track global value uses

GlobalValues are often interesting, especially if they have local
linkage. We now track all uses of those and refine potential callees
with it. Effectively, if an internal function cannot reach an indirect
call site, it cannot be a potential callee, even if it has its address
taken.
