## Message

```
stage2 parser: don't append doc comments to the list

The DocComment AST node now only points to the first doc comment token.
API users are expected to iterate over the following tokens directly.

After this commit there are no more linked lists in use in the
self-hosted AST API.

Performance impact is negligible. Memory usage slightly reduced.
