Rustc pull update

update autodiff install docs for nix

Fix typo in best-practices.md

update `FIXME(static_mut_refs)` comment to say: use raw pointers instead of references.

Because we use `ThinVec` rather than `Vec` almost everywhere else in the AST.

The unstable attribute on Read::read_le and Read::read_be pointed to the implementation PR rather than the tracking issue, so the docs on doc.rust-lang.org linked to the wrong page.
