C# Class Rakudo.Metamodel.Representations.P6opaque

This is a first cut implementation of the P6opaque representation. Eventually it's going to need to handle native types too, and we want to get an instance down to a single object allocation if we can. Alas, that's Quite Tricky to write, so for now we just do something easy, but at least with the hints.

bind_attribute_with_hint ( ThreadContext TC, RakudoObject Object, RakudoObject ClassHandle, string Name, int Hint, RakudoObject Value ) : void	Bind the attribute, using the hint if possible.
defined ( ThreadContext TC, RakudoObject Object ) : bool	Checks if the object is defined, which boils down to "is this a type object", which in trun means "did we allocate any storage".

instance_of ( ThreadContext TC, RakudoObject WHAT ) : RakudoObject	Allocates and returns a new object based upon the type object supplied. Also, computes the slot allocation if we didn't do that yet.
