Function.js bind_bindFunction{0,1,2} are special cases of the generic bind_bindFunctionN below. They avoid the need to merge the lists of bound arguments and call arguments to the bound function into a new list which is then used in a destructuring call of the bound function. All three of these functions again have special-cases for call argument counts between 0 and 5. For calls with 6+ arguments, all - bound and call - arguments are copied into an array before invoking the generic call and construct helper functions. This avoids having to use rest parameters and destructuring in the fast path. Directly embedding the for-loop to combine bound and call arguments may inhibit inlining of the bound function, so we use a separate combiner function to perform this task. This combiner function is created lazily to ensure we only pay its construction cost when needed. All bind_bindFunction{X} functions have the same signature to enable simple reading out of closed-over state by debugging functions. Note: We use the '$' prefix on the function to force it to be an extended function so that `finishBoundFunctionInit` can track length. 13821

MapObject.h Comparing two ropes for equality can fail. The js::HashTable template requires infallible hash() and match() operations. Therefore we require all values to be converted to hashable form before being used as a key in a Map or Set object. All values except ropes are hashable as-is. 17782

Promise-inl.h Given a settled (i.e. fulfilled or rejected, not pending) promise, sets |promise.[[PromiseIsHandled]]| to true and removes it from the list of unhandled rejected promises.

Promise.h Unforgeable version of the JS builtin Promise.all. Takes a HandleValueVector of Promise objects and returns a promise that's resolved with an array of resolution values when all those promises have been resolved, or rejected with the rejection value of the first rejected promise. Asserts that all objects in the `promises` vector are, maybe wrapped, instances of `Promise` or a subclass of `Promise`. 10588
