bors 84e42fb363 Auto merge of #10484 - Alexendoo:format-args-ast-2, r=Manishearth
Migrate `format_args.rs` to `rustc_ast::FormatArgs`

changelog: none

Part of https://github.com/rust-lang/rust-clippy/issues/10233

Empty precision specifiers are no longer linted as the span for that isn't present in [`FormatOptions`](https://doc.rust-lang.org/nightly/nightly-rustc/rustc_ast/format/struct.FormatOptions.html)

```rust
format!("{:.}", ...)
```

That could be fixed later with some hackery or a change upstream
