Motivation for this change
Dependency cycle between semigroups and QuickCheck:
The specific cycle is part of the commit message. I simply disabled the test suites for hashable and unordered-containers altogether. I'm not sure if there is a better way.
Removing obsolete packages from configuration:
There are a few references to specific versions of packages in
configuration-ghc-7.10.x.nix. Many (most?) of them are not included inhackage-packages.nixand fail to evaluate. I deleted those which where only referenced by themselves. That seemed reasonable, but there are more occurrences e.g. in ghc-mod which also don't evaluate. I'm not sure what the general process is in regards to this.Things done
