-- Moves promiseHasHandlerSymbol to inobject property
-- Ports PromiseResolveClosure to TF
-- Fix a non spec async-await test which fails now because we do a map
check for native promise check (instead of IsPromise). Changing the
constructor (in the test) invalidates the map check.

This patch results in a 7.1% performance improvement in the bluebird
benchmark (over 5 runs).

- Creates a new promise-utils.{h, cc} which refactors out the
logic to create resolving functions. This is shared between the
runtime functions and builtins.

- Changes PromiseResolveThenableJobInfo to store the context
since we no longer create the resolving functions in JS.

- Changes EnqueuPromiseResolveThenableJob to take in the promise and
  not the callbacks.
