Hello! I've updated Dual-Pivot Quicksort, Sorting and Arrays classes, please review.
http://cr.openjdk.java.net/~alanb/6976036/webrev In compare with previous version (JDK 7 vs. JDK 6) the ratio is: 52.14% for client and 41.62% for server VM (was 57.22% and 46.18%). Summary of changes: 1. Range check was moved from DualPivotQuicksort to Arrays class. 2. Pair insertion sort is used for sorting small arrays instead of traditional. 3. Added new test in Sorting class: compare with insertion sort on small arrays. 4. Minor cosmetic changes. Thank you, Vladimir
