==== C stack trace ===============================


Original change's description:
> [builtins] don't inline calls for common Promise ops in async builtins
> 
> InternalResolvePromise, InternalPromiseReject and
> InternalPerformPromiseThen generate quite a lot of code.
> 
> This change adds 3 new TF stubs which inline calls to these builtins.
> These stubs are invoked rather than inlining those operations listed
> above directly. This is done for Async Iteration builtins, as well as
> Async Function builtins. Promise builtins are left as they were, and
> continue to inline these calls.
> 
> This results in a roughly 99kb reduction in snapshot_blob.bin on an x64
> release build.
