Compact Regions
This brings in initial support for compact regions, as described in the ICFP 2015 paper "Efficient Communication and Collection with Compact Normal Forms" (Edward Z. Yang et.al.) and implemented by Giovanni Campagna. Some things may change before the 8.2 release, but I (Simon M.) wanted to get the main patch committed so that we can iterate. What documentation there is is in the Data.Compact module in the new compact package. We'll need to extend and polish the documentation before the release. Test Plan: validate (new test cases included) Reviewers: ezyang, simonmar, hvr, bgamari, austin Subscribers: vikraman, Yuras, RyanGlScott, qnikst, mboes, facundominguez, rrnewton, thomie, erikd Differential Revision: https://phabricator.haskell.org/D1264 GHC Trac Issues: #11493
