Nicholas Nethercote 4ebf2be8bb Remove Iterator impl for TokenTreeCursor. 
This is surprising, but the new comment explains why. It's a logical
conclusion in the drive to avoid `TokenTree` clones.

`TokenTreeCursor` is now only used within `Parser`. It's still needed
due to `replace_prev_and_rewind`.

README.md

The rustc_ast crate contains those things concerned purely with syntax – that is, the AST ("abstract syntax tree"), along with some definitions for tokens and token streams, data structures/traits for mutating ASTs, and shared definitions for other AST-related parts of the compiler (like the lexer and macro-expansion).

For more information about how these things work in rustc, see the rustc dev guide:
