    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.
