[Streams API] Rework some readable stream internals that can be common to writable streams
https://bugs.webkit.org/show_bug.cgi?id=150133
Reviewed by Darin Adler.
Source/JavaScriptCore:
* runtime/CommonIdentifiers.h:
* runtime/JSGlobalObject.cpp:
(JSC::JSGlobalObject::init): Added RangeError also as native functions.
Source/WebCore:
There are some things in ReadableStream internals that be be used also for Writable Streams so it was necessary
to move some functions and refactor some code that can be shared by both implementations.
Queue was written with the functions declared at the implementation and keeping the improvement of having the
total size calculated instead of having to transverse the whole array.
The strategy is kept as an object and a common method is used to validate it as per spec.
Promises are reworked to keep in an internal slot inside the promise object the resolve and reject
functions. For convinience three functions were written, one to create the promise (and keep internally the
resolve and reject functions), one to resolve and another to reject. Promises can still be created with
Promise.resolve or reject as the resolve and rejectStreamsPromise functions operate under the assumption that
the internal slots might not exist.
invokeOrNoop and promiseInvokeOrNoop were moved to the common code as they will be also used by WritableStream.
Current test set suffices.
