This CL adds a bit more rigor to the handling of length properties in JSObject-derived classes that explicitly contain that property inline. This involves: - Introducing a new superclass of JSArgumentsObject called JSArgumentsObjectWithLength that is shared with other object instances that also have a fixed length property. - Adding JSArgumentsObjectWithLength to the type hierarchy in Torque, including adding fast-cases for leading the length property for all classes deriving from JSObjectWithLength. - Adding more rigor to Context and NativeContext handling in base.tq. This is useful for the map checks required to verify objects are argument object types derived from JSArgumentsObjectWithLength.
