I'd like to deprecate and remove the Link class,
as best as I can tell, it doesn't offer the same
performance benefits as I've seen on other platforms.
Fasta mostly uses "null" to represent empty lists, and
after the old dart2js front was deleted, there are few
uses remaining.
This CL makes it easier to find the remaining uses.
