These represent the outermost scope in the environment record hierarchy. The spec says they should be a "composite" of two things: - An ObjectEnvironmentRecord wrapping the global object - A DeclarativeEnvironmentRecord for other declarations It's not yet clear to me how this should work, so this patch only implements the first part, an object record wrapping the global object.
