 Tests for ra_syntax are mostly data-driven.
 `test_data/parser` contains subdirectories with a bunch of `.rs` (test vectors) and `.txt` files with corresponding syntax trees.
 During testing, we check `.rs` against `.txt`.
 If the `.txt` file is missing, it is created (this is how you update tests).
-Additionally, running `cargo xtask codegen` will walk the grammar module and collect all `// test test_name` comments into files inside `test_data/parser/inline` directory.
