	Description:

	VM representation of Smalltalk LinkedList class, and its links (LinkedList
	uses intrusive linking).

	N.B. The classes here defined are well known to the VM, and must not
	be modified in the image. Note also that these classes may also have
	a representation in the assembler modules (so see istasm.inc)
