Hmm, breaking one decl rule.  tree-inliner used to do that years ago, too. When function declaring
extern in local scope got inlined, we duplicated the node.  I fixed that by pushing these to
nonlocalized_list instead.

Perhaps we could do that earlier, in FE (or fixup in free lang data), for all EXTERn decls
avoiding those duplications.
