Now that we sometimes know the address space, this can theoretically do a better job. This needs better test coverage, but this mostly depends on first updating the loop optimizatiosn to provide the address space. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@239053 91177308-0d34-0410-b5e6-96231b3b80d8
