r117859 introduced a preliminary implementation of ES6-like private name objects to JSC. These are probably not yet ready to be web-facing, so disabling by default in WebCore.
Opting-in for JSC & DumpRenderTree so that we can still run the fast/js/names.html test.

Fixed in r118018
After disabling private names, fast/js/names.html started to fail on GTK and Qt, because r118018 made the necessarry changes to be able run this test for Mac only.
I skipped this test on Qt - r118130.
