r=me.
It might be good to improve the controller code.
See below for all possible improvements.
This can be done now or in a later patch.
Wdyt romain?

These two includes may no longer be needed

Can we add an ASSERT(isLocked.isFunction())?

Can we add a jsConstroller() method helper that would do 
ASSERT(m_jsController);
Return m_jsController;

Might be better to return a reference than a pointer.

> Source/WebCore/bindings/js/ReadableStreamDefaultController.h:72
> +    return static_cast<JSDOMGlobalObject*>(m_jsController->globalObject());

Might be better to add an ASSERT and return a JSDOMGlobalObject&

> Source/WebCore/bindings/js/ReadableStreamDefaultController.h:77
> +    JSC::ExecState& state = *globalObject()->globalExec();

Might be good to add an ASSERT(globalObject()->globalExec())

> Source/WebCore/bindings/js/ReadableStreamDefaultController.h:96
> +    JSC::JSLockHolder locker(state);

Ditto.

Switch reader and controller lines?

For this patch I was focusing on the JS part. I just uploaded a new patch that fixes alphabetical order in WebCoreBuiltinNames.h, but I let other remarks aiming at improving ReadableStreamDefaultController.h/cpp for another patch. I'm going to create a bug about that.
