What do you think about introducing regression tests with test262-parser-runner?

First of all thank you for working on this acorn plugin for typescript.

I personally ran test262-parser-runner, which is also used by Acorn, on acorn-typescript fork repository and found some errors.

Some tests still seem to fail, but I think it makes sense to introduce test262 so that we can share with you what is failing.

OK, I will handle this problems

I think we have introduced test262 and tested it, so I'm closing this issue. Thank you!
