A more flexible container for storing overrides is required for headers. Before a source goes through the transform pipeline, any headers it references will be in their original state and unaffected by transforms applied to other sources. Therefore overrides for headers need to be kept separate for each source file. This patch doesn't introduce support for storing header overrides yet. It only replaces the existing structure and makes any necessary changes to support it. llvm-svn: 183910
