Add string comparators that can compare ASCII strings ignoring case.

Also add comparators that compare digit sequences lexicographically
(which is the same as comparing numerically if there are no leading
zeros).
The comparison functions define total orderings, breaking ties for
strings that only differ by case by their first case-different letter,
upper-case being less than lower-case.
