Introduces a new layer interface, LinkGraphLayer, that can be used to add LinkGraphs to an ExecutionSession. This patch moves most of ObjectLinkingLayer's functionality into a new LinkGraphLinkingLayer which should (in the future) be able to be used without linking libObject. ObjectLinkingLayer now inherits from LinkGraphLinkingLayer and just handles conversion of object files to LinkGraphs, which are then handed down to LinkGraphLinkingLayer to be linked.
