Introduce overflow-safe integer comparison functions.
This commit adds integer comparison functions that are designed to
be as efficient as possible while avoiding overflow. A follow-up
commit will make use of these functions in many of the in-tree
qsort() comparators. The new functions are not better in all cases
(e.g., when the comparator function is inlined), so it is important
to consider the context before using them.
