Make user-exposed sorts stable, by storing the position of elements in the original array, and using those positions as a fallback comparison criterion. The base sort is still hybrid q/insert. The use of true/false comparison functions is deprecated (but still supported) and should be replaced by -1/0/1 comparison functions, driven by the <=> operator. RFC: https://wiki.php.net/rfc/stable_sorting Closes GH-5236.
