* implementation wraps it in a RuntimeException.

- {@code NEW_INSTANCE} returns a new instance of the protocol buffer that has not yet been
* made immutable. See {@code MAKE_IMMUTABLE}.
*
- {@code IS_INITIALIZED} is parameterized with a {@code Boolean} detailing whether to
* memoize. It returns {@code null} for false and the default instance for true. We optionally
* memoize to support the Builder case, where memoization is not desired.
*
- {@code NEW_BUILDER} returns a {@code BuilderType} instance.
*
- {@code VISIT} is parameterized with a {@code Visitor} and a {@code MessageType} and
* recursively iterates through the fields side by side between this and the instance.

- {@code MAKE_IMMUTABLE} sets all internal fields to an immutable state.
