async/await: Don't trigger uncaught rejection handlers on throwaway Promises This patch implements a bug fix to the async/await specification described at https://github.com/tc39/ecma262/pull/692#issuecomment-247488411 Namely, the intermediate values of Promises may be rejected, and they do not have .then called on them anymore (now that the memory leak is fixed), but they do not correspond do unhandled rejections. This change has been tested manually with integration with Blink; once it is checked in and rolled, then further tests can be added on the Blink side for the uncaught rejection handler and async/await.
