Restore Trees That Grow reverted commits
The following commits were reverted prior to the release of GHC 8.4.1,
because the time to derive Data instances was too long [1].

e3ec2e7ae94524ebd111963faf34b84d942265b4 Phab:D4177
47ad6578ea460999b53eb4293c3a3b3017a56d65 Phab:D4186
The work is continuing, as the minimum bootstrap compiler is now
GHC 8.2.1, and this allows Plan B[2] for instances to be used. This
will land in a following commit.
Updates Haddock submodule
