From 1a4761edca58c6b559de825b9abfb66f7f1ba94a Mon Sep 17 00:00:00 2001
From: Douglas Gregor <dgregor@apple.com>
Date: Wed, 30 Nov 2011 23:21:26 +0000
Subject: Promote ModuleMap::Module to a namespace-scope class in the Basic
 library, since modules cut across all of the libraries. Rename
 serialization::Module to serialization::ModuleFile to side-step the annoying
 naming conflict. Prune a bunch of ModuleMap.h includes that are no longer
 needed (most files only needed the Module type).
