Nicholas Nethercote c290293cf2 Derive Rustc{En,De}codable for TokenStream. ... `TokenStream` used to be a complex type, but it is now just a newtype around a `Lrc<Vec<TreeAndJoint>>`. Currently it uses custom encoding that discards the `IsJoint` and custom decoding that adds `NonJoint` back in for every token tree. This requires building intermediate `Vec<TokenTree>`s. This commit makes `TokenStream` derive `Rustc{En,De}codable`. This simplifies the code, and avoids the creation of the intermediate vectors, saving up to 3% on various benchmarks. It also changes the AST JSON output in one test.		2019-10-21 06:54:41 +11:00
