    [SCEV] Don't expand Wrap predicate using inttoptr in ni addrspaces

    Summary:
    In non-integral address spaces, we're not allowed to introduce inttoptr/ptrtoint
    intrinsics. Instead, we need to expand any pointer arithmetic as geps on the
    base pointer. Luckily this is a common task for SCEV, so all we have to do here
    is hook up the corresponding helper function and add test case.

    Fixes PR38290
