Reviewed by Mike Wyrzykowski.

Since the original implementation 3 new language features/extensions were added
to the spec[1]. We already implemented most of them, two of them, so it was just
a matter of adding them to the enum, but `pointer_composite_access` had to be
implemented, which in short allows accessing pointers to composite types in the
same way as references.
