<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Use Semigroup's (<>) for Doc/SDoc
Before this patch, Outputable.hs defined its own (<>) which caused
conflicts with (Data.Semigroup.<>) and thus led to inconvenience.
However, replacing it is not trivial due to a different fixity:
http://www.haskell.org/pipermail/libraries/2011-November/017066.html
Nevertheless, it is possible to update the pretty-printing code to work
with (<>) of a different fixitiy, and that's what this patch implements.
Now Doc and SDoc are instances of Semigroup.
