RFR: 8325679: Optimize ArrayList subList sort

[Attila Szegedi]

Somewhat surprisingly, `ArrayList$Sublist.sort()` is not specialized and will thus fall back to slower default method of `List.sort()` instead of sorting a range of the array in-place in its backing root `ArrayList`. 

This doesn't change observable behavior, so haven't added tests, and `tier1` tests still all pass except for `test/jdk/java/util/Locale/LocaleProvidersFormat.java` which also currently fails on master too on the machine I tested on.
