Unrolled build for rust-lang#120316

Rollup merge of rust-lang#120316 - GuillaumeGomez:fix-ast-visitor, r=compiler-errors

Don't call `walk_` functions directly if there is an equivalent `visit_` method

I was working on rust-lang#77773 and realized in one of my experiments that the `visit_path` method was not always called whereas it should have. This fixes it.
