  [LAA] Consider accessed addrspace when mapping underlying obj to access. (#129087)

In some cases, it is possible for the same underlying object to be
accessed via pointers to different address spaces. This could lead to
pointers from different address spaces ending up in the same dependency
set, which isn't allowed (and triggers an assertion).

Update the mapping from underlying object -> last access to also include
the accessing address space.

Fixes https://github.com/llvm/llvm-project/issues/124759.
