Some Objective-C JSC API tests are failing on Mountain Lion bots after the API was enabled in <http://trac.webkit.org/r156811>. See for example <http://build.webkit.org/builders/Apple%20MountainLion%20Debug%20WK1%20%28Tests%29?numbuilds=50>. For the API to work, the tests need to be compiled with a newer version of the LLVM compiler. Until the bots are updated to that version, I am going to disable the tests on 10.8.
