Import tests from TC39 tests262

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:

This is really exciting issue!
As far as I know, we can execute each test262 test by executing it with the test harness script. So I think we can adopt test262 into JSC tests :D

I'll check the current W3C test import process...
