// Representation of promise objects in the specification. Our layout of
// JSPromise differs a bit from the layout in the specification, for example
// there's only a single list of PromiseReaction objects, instead of separate
// lists for fulfill and reject reactions. The PromiseReaction carries both
// callbacks from the start, and is eventually morphed into the proper kind of
// PromiseReactionJobTask when the JSPromise is settled.
//
// We also overlay the result and reactions fields on the JSPromise, since
// the reactions are only necessary for pending promises, whereas the result
// is only meaningful for settled promises.
