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.
