  Changed paths:
    M llvm/lib/Analysis/Loads.cpp
    M llvm/unittests/Analysis/CMakeLists.txt
    A llvm/unittests/Analysis/LoadsTest.cpp

  Log Message:
  -----------
  [Loads] Handle simple cases with same base pointer with constant offsets in FindAvailableLoadedValue when AA is null.

Summary:
This will help with devirtualization (store forwarding with vtable pointers in
the presence of other stores into members in the constructor.) During inlining,
we don't have AA.
