MacroInfo*. Instead of simply dumping an offset into the current file, give each macro definition a proper ID with all of the standard modules-remapping facilities. Additionally, when a macro is modified in a subsequent AST file (e.g., #undef'ing a macro loaded from another module or from a precompiled header), provide a macro update record rather than rewriting the entire macro definition. This gives us greater consistency with the way we handle declarations, and ties together macro definitions much more cleanly. Note that we're still not actually deserializing macro history (we never were), but it's far easy to do properly now. llvm-svn: 165560
