    PR25018, readelf crash on 32bits

    Pointer comparisons after adding an offset just don't work to catch
    overflow when the offset is a larger type than the pointer.

        PR 25018
        * dwarf.c (get_type_signedness): Delete ineffective pointer
        comparison check.  Properly range check uvalue offset on
        recursive call.
        (read_and_display_attr_value): Range check uvalue offset before
        calling get_type_signedness.
