        * tree-vrp.c (adjust_range_with_scev): Do not use TYPE_{MIN,MAX}_VALUE
        for pointer types.
        * tree-scalar-evolution.c (fold_used_pointer_cast, pointer_offset_p,
        fold_used_pointer, pointer_used_p): New functions.
        (analyze_scalar_evolution_1): Use fold_used_pointer.
        * tree-chrec.c (convert_affine_scev): Convert no-op casts correctly.
        * tree-ssa-loop-ivopts.c (generic_type_for): Return integral type
        for pointers.

I'll backport the vrp changes.
