Auto merge of #81453 - jumbatm:clashing-extern-decl-perf, r=nagisa
clashing_extern_declarations: Use symbol interning to avoid string alloc. Use symbol interning as a hack to avoid allocating a string for every symbol name we store in the seen set. This hopefully addresses the minor perf regression described in https://github.com/rust-lang/rust/pull/80009#issuecomment-763526902. r? `@nagisa`
