`TokenCursor` currently does doc comment desugaring on the fly, if the `desugar_doc_comment` field is set. This requires also modifying the token stream on the fly with `replace_prev_and_rewind`. This commit moves the doc comment desugaring out of `TokenCursor`, by introducing a new `TokenStream::desugar_doc_comment` method. This separation of desugaring and iterating makes the code nicer. |

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:
