commit 03b380428c128b12aef07a9b67341803ef0bea76
Author: Herbert Valerio Riedel <hvr at gnu.org>
Date:   Sun Sep 27 12:01:41 2015 +0200

    Add Data.Semigroup and Data.List.NonEmpty (re #10365)
    
    This implements phase 1 of the semigroup-as-monoid-superclass
    proposal (https://ghc.haskell.org/wiki/Proposal/SemigroupMonoid).
    
    The modules were migrated from the `semigroups-0.17` release mostly
    as-is, except for dropping several trivial `{-# INLINE #-}`s,
    removing CPP usage, and instances for types & classes provided
    outside of `base` (e.g. `containers`, `deepseq`, `hashable`, `tagged`,
    `bytestring`, `text`)
