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].

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
