We should import tests from https://github.com/tc39/test262

Their tests for class syntax, for example, caught a few bugs as well as crashes!
I've been using their python script to run tests as follows:
./tools/packaging/test262.py --command="/Volumes/Data/webkit/Tools/Scripts/run-jsc --no-show-dyld"

after applying the following change to run-jsc:
