Subject: Replace Sema's map of locally-scoped extern "C" declarations with a
 DeclContext of extern "C" declarations. This is simpler and vastly more
 efficient for modules builds (we no longer need to load *all* extern "C"
 declarations to determine if we have a redeclaration).

No functionality change intended.
