Add deepseq dependency and a few NFData instances

I needed to rnf a data structure (CompiledByteCode) but we don't have
any good deepseq infrastructure in the compiler yet.  There are bits and
pieces, but nothing consistent, so this is a start.

We already had a dependency on deepseq indirectly via other packages
(e.g. containers).

Includes an update to the haddock submodule, to remove orphan NFData
instances in there.
