Motivation for this change
I want a recent version for trying out https://gitlab.haskell.org/ghc/ghc/merge_requests/668
I'm not entirely sure on the version naming, I chose 8.9 because 8.8 is branched off already, and HEAD will once become 8.10
I included the patch not propagated in e001b99, because I still ran into haskell/haddock#900 when compiling the polysemy-zoo package, see commercialhaskell/stackage#4562 (comment). Not entirely sure why that patch doesn't appear to be in HEAD.
Since recent times, current ghcHEAD failed in nixpkgs, see https://hydra.nixos.org/job/nixos/trunk-combined/nixpkgs.haskell.compiler.ghcHEAD.x86_64-linux, but this updated versions builds just fine.
