Unrolled build for rust-lang#133188

Rollup merge of rust-lang#133188 - maxcabrajac:walk_no_visit, r=petrochenkov

Add `visit` methods to ast nodes that already have `walk`s on ast visitors

Some `walk` functions are called directly, because there were no correspondent visit functions.

related to rust-lang#128974 & rust-lang#127615
