Reland "[api] allow v8::Data as internal field"
This is a reland of commit 0aa622e12893e9921c01a34ce9507b544e599c4a
The original patch tried to run a test that calls exit() in the
fatal error handler in parallel, which would not work. This marked
the test with TEST() to avoid running it in parallel.
Original change's description:
> [api] allow v8::Data as internal field
>
> Previously only v8::Value can be stored as internal fields.
> In some cases, however, it's necessary for the embedder to
> tie the lifetime of a v8::Data with the lifetime of a
> JS object, and that v8::Data may not be a v8::Value, as
> it can be something returned from the V8 API. One way to
> keep the v8::Data alive may be to use a v8::Persistent<v8::Data>
> but that can easily lead to leaks.
>
> This patch changes v8::Object::GetInternalField() and
> v8::Object::SetInernalField() to accept v8::Data instead of just
> v8::Value, so that v8::Data can kept alive by a JS object in
> a way that the GC can be aware of to address this problem.
> This is a breaking change for embedders
> using v8::Object::GetInternalField() as it changes the return
> type. Since most v8::Value subtypes only support direct casts
> from v8::Value but not v8::Data, calls like
>
> object->GetInternalField(index).As<v8::External>()
>
> needs to be updated to cast the value to v8::Value first:
>
> object->GetInternalField(index).As<v8::Value>().As<v8::External>()
