From 851ba39dab544ad986f150aec9573add9d978397 Mon Sep 17 00:00:00 2001
From: Chris Lattner <sabre@nondot.org>
Date: Wed, 17 Dec 2008 21:39:50 +0000
Subject: [PATCH] This adds some missing functions to the C binding: - ability
 to insert previously created instructions using a builder - creation of
 aliases - creation of inline asm constants

Patch by Zoltan Varga!
