Original commit message:

    Drop UniqueId from include/v8.h

    It's unused since March 2 2017 (https://chromium-review.googlesource.com/448539).
    This removes it assuming that leaving it in the header was an oversight.

Original commit message:

    Remove experimental fast accessor builder API

    As the code isn't used, but would have to be ported from hand-written
    assembly to CodeStubAssembler anyways, I propose to remove it and
    restore it if we decide that we actually need it.

Original commit message:

    Make v8::Eternal::Get and IsEmpty const.

    They do not modify the state of the handle.

Ref: v8/v8@3700a01c82

Original commit message:

    Give v8::Eternal a direct reference to the handle.

    This makes it more similar to other handle types (like PersistentBase),
    by simply storing an i::Object** cast to T*. This means that it is not
    necessary to look up the handle in the eternal handles table to access
    the underlying value.

    Like the built-in roots (null, etc.), an eternal handle can never be
    destroyed, so we don't even need to allocate a separate local handle.
    Instead, the Local<T> can point directly at the eternal reference.
    This makes Eternal<T>::Get trivial.
