[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.
