This is Abstract Operation is required for the majority of InstantConstructor's and InstantPrototype's methods. The implementation is not entirely complete, (specifically 2 of the underlying required abstract operations, ParseTemporalTimeZoneString and ParseISODateTime are missing the required lexing, and as such are TODO()-ed) but the majority of it is done.
