Fixes a miscompile when the index of `index_addr` is a negative integer constant. In this case two access paths were considered overlapping while in reality they reference two different array elements. The miscompile manifested in the dead-store-elimination pass, but could potentially also show up in other passes, which use this utility. https://github.com/swiftlang/swift/issues/77558 rdar://176820188
