`visit_local` is the only method that doesn't call a corresponding `super_local` method. This is valid, because `super_local` would be empty. But it's inconsistent with every other case; we have multiple other empty `super` methods: `super_span`, `super_ty`, etc. This commit adds an empty `super_local` and makes `visit_local` call it.
The `MirVisitable` trait is just a complicated way to visit either a statement or a terminator. (And its impl for `Terminator` is unused.) It has a single use. This commit removes it, replacing it with an if/else, which is shorter and simpler.
rustfmt doesn't touch it because it's a macro body, but it's large enough that the misformatting is annoying. This commit improves it. The most common problems fixed: - Unnecessary multi-line patterns reduced to one line. - Multi-line function headers adjusted so the parameter indentation doesn't depend on the length of the function name. (This is Rust code, not C.) - `|` used at the start of lines, not the end. - More consistent formatting of empty function bodies. - Overly long lines are broken.
