Stop emulating cross-crate hygiene with gensyms
Most `Ident`s are serialized as `InternedString`s the exceptions are: * Reexports * Attributes * Idents in macro definitions Using gensyms helped reexports emulate hygiene. However, the actual item wouldn't have a gensymmed name so would be usable cross-crate. So removing this case until we have proper cross-crate hygiene seems sensible. Codegen attributes (`inline`, `export_name`) are resolved by their `Symbol`. This meant that opaque macro-expanded codegen attributes could cause linker errors. This prevented making built-in derives hygienic.
