Rollup merge of #150205 - Enselic:line-no, r=Zalathar,jieyouxu compiletest: Add `LineNumber` newtype to avoid `+1` magic here and there Start small. If it works well we can increase usage bit by bit as time passes. My main motivation for doing this is to get rid of the `+ 1` I otherwise have to add in https://github.com/rust-lang/rust/pull/150201 on this line: ```rs crate::directives::line::line_directive(file, zero_based_line_no + 1, &line) ``` But I think this is a nice general improvement by itself. Note that we keep using "0" to represent "no specific line" because changing to `Option<LineNumber>` everywhere is a very noisy and significant change. That _can_ be changed later if wanted, but let's not do it now.

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.
Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrated with other languages.
Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.
Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
