Revert "Use std::stable_sort() instead of std::sort()" Unfortunatly std::stable_sort() implementation in gcc is horrendously slow. We have a big performance regression on Linux systems (-20% !) So revert the commit and wait to fix the issue in a different way, perhaps with an our home grown sorting, that should be comparable in speed with std::sort() Signed-off-by: Marco Costalba <mcostalba@gmail.com>
