Add support for Promises
https://bugs.webkit.org/show_bug.cgi?id=120260
Reviewed by Darin Adler.
Source/JavaScriptCore:
Add an initial implementation of Promises - http://dom.spec.whatwg.org/#promises.
- Despite Promises being defined in the DOM, the implementation is being put in JSC
in preparation for the Promises eventually being defined in ECMAScript.

Add new files.
Update jsc's GlobalObjectMethodTable to stub out the new QueueTaskToEventLoop callback. This mean's
you can't quite use Promises with with the command line tool yet.
