Johannes Doerfert 5ee3942ae7 [Attributor] Introduce getPotentialCopiesOfStoredValue and use it 
This patch introduces `getPotentialCopiesOfStoredValue` which uses
AAPointerInfo to determine all "aliases" or "potential copies" of a
value that is stored into memory. This operation can fail but if it
succeeds it means we can visit all "uses" of a value even if it is
temporarily stored in memory.

There are two users for the function:
  1) `Attributor::checkForAllUses` which will now ignore the value use
     in a store if all "potential copies" can be identified and instead
     be visited. This allows various AAs, including AAPointerInfo
     itself, to look through memory.
  2) `AANoCapture` which uses a custom use tracking through the
     CaptureTracker interface and therefore needs to be thought
     explicitly.

The LLVM Compiler Infrastructure
================================

This directory and its subdirectories contain source code for LLVM,
a toolkit for the construction of highly optimized compilers,
optimizers, and runtime environments.

LLVM is open source software. You may freely distribute it under the terms of
the license agreement found in LICENSE.txt.

Please see the documentation provided in docs/ for further
assistance with LLVM, and in particular docs/GettingStarted.rst for getting
started with LLVM and docs/README.txt for an overview of LLVM's
documentation setup.

If you are writing a package for LLVM, see docs/Packaging.rst for our
suggestions.
