From 25209b40cbff14093adc4f0b47f0060e44e18752 Mon Sep 17 00:00:00 2001
From: Owen Anderson <resistor@mac.com>
Date: Wed, 1 Jul 2009 16:58:40 +0000
Subject: Add a pointer to the owning LLVMContext to Module.  This requires
 threading LLVMContext through a lot of the bitcode reader and ASM parser
 APIs, as well as supporting it in all of the tools.

Patches for Clang and LLVM-GCC to follow.
