Instead of modifying the ObjC AST to not modify existing declarations, teach chained PCH to overwrite declarations from earlier PCH files in dependent ones. Tell Sema to note when it changes AST nodes so that they have to be reserialized. Finally, the ObjCProtocolDecls created in forward decls, like the ObjCInterfaceDecls in @class forward decls, are not lexically part of the decl context; only the definition is.

gcc-built objects with clang-built objects, and the optimization isn't really
that valuable.  Platforms with less ornery linkers can feel free to enable this.

initialization/finalization with its various consumers and external
sources into the Sema constructor and destructor, rather than placing
it in ParseAST.

- New 'CanVary' heuristic to recursively determine if a subexpression has a varying element
- Updated test cases, including one known bug

just those that are enforced by hardware.  Please let us know if this causes
major problems for you (which it shouldn't, since it's an optional warning).
