Regis Crelier 3633c5bd5e Rename Closure instance field type_arguments_ to instantiator_.
Simplify handling of closures as deferred objects.
The name "type_arguments_" is confusing, because class Closure is not generic.
Class Closure was forcefully made (kinda) generic by setting its
type_arguments_field_offset_in_words_ field to a valid value, so that the
type_arguments_ field in closure instances could be accessed similarly as in
generic instances. With generic functions, closures will potentially have more
than one instantiator and the name type_arguments_ becomes nonsensical.
