    PR10719 cont'd: const-fold comparisons
    
    We can compute results between two literals, and we can also compute
    comparisons to boundary numbers.
    
    (We could also check boundary strings, "" and "\377\377...", but even
    I am not THAT pedantic... yet...)
    
    * elaborate.cxx (const_folder::visit_comparison): Implement.
