<pre>To provide information to the inspector, JS builtins should have some sort of instrumentation system.
In this patch, we'll introduce a new private namespace object (like Reflect/Math) @InspectorInstrumentation into the builtin JS.
It gives the instrumentation ability to the builtin JS code in JSC.
Here's my design.
In @fulfillPromise in Operation.Promise.js,
function fulfillPromise(...)
{
...
@InspectorInstrumentation.promiseFulfilled(promise);
...
}
And in InspectorInstrumentationObject.js (builtin JS code),
function promiseFulfilled(promise)
{
if (!this.isEnabled)
return;
this.promiseFulfilledImpl(promise); // call C++ code / other inspector code
}</pre>
