Results of perf-tests for selection in CSS Regions

These are the results of running the performance tests in a simple document with and without CSS Regions.

The first 3 runs were executed in trunk and the last 3 were executed in trunk without the patch for bug #105641 (r139197).

In trunk the performance of the selection in documents with CSS Regions seems better than in normal documents, I guess that the reason is that when you're selecting different flow threads the execution enter in the diff at RenderView::setSelection() related to the flow threads (see http://trac.webkit.org/browser/trunk/Source/WebCore/rendering/RenderView.cpp#L728). However, without that if (patch for bug #105641) the performance in documents with CSS Regions seems worse.
