Original change's description:

> This is a reland of b022e825

> Original change's description:
> > [builtins] Verify Isolate compatibility with the embedded blob
> >
> > Embedded builtins (= the embedded blob) have a few dependencies on the
> > snapshot state. For instance, they require that metadata stored on
> > builtin Code objects as well as the builtins constant table remain
> > unchanged from mksnapshot-time. Embedders may violate these
> > assumptions by accident, e.g. by loading a snapshot generated with
> > different build flags, leading to seemingly unrelated failures later
> > on.
> >
> > This CL introduces an Isolate hash stored in the embedded blob which
> > hashes relevant parts of builtin Code objects and the builtins
> > constant table. It's verified in Isolate::Init in debug builds.
