Summary Several fast/selectors tests are very slow in debug

These tests are so slow that that they frequently time out on bots an locally, especially when other tests run in parallel using hyper-threading. fast/selectors/matches-backtracking.html took 44.6 seconds fast/selectors/nth-child-of-register-requirement.html took 24.3 seconds fast/selectors/not-backtracking.html took 23.5 seconds This one may or may not have the same root cause, I imagine that jquery does a lot of CSS selector matching. jquery/manipulation.html took 23.0 seconds

Marked as slow in <http://trac.webkit.org/r177271>. This may not fully help, as some ports appear to detect a timeout at another layer, and report the test as "failing".
