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.
