Auto merge of #5378 - Centril:unnested-or-pats, r=flip1995,phansch
New lint: `unnested_or_patterns` changelog: Adds a lint `unnested_or_patterns`, suggesting `Some(0 | 2)` as opposed to `Some(0) | Some(2)`. The lint only fires on compilers capable of using `#![feature(or_patterns)]`. - The lint is primarily encoded as a pure algorithm which to unnest or-patterns in an `ast::Pat` (`fn unnest_or_patterns`) through a `MutVisitor`. After that is done, and assuming that any change was detected, then `pprust::pat_to_string` is used to simply convert the transformed pattern into a suggestion. - The PR introduces a module `utils::ast_utils` with a bunch of functions for spanless & nodeless equality comparisons of ASTs. cc https://github.com/rust-lang/rust/issues/54883
