UI tests: migrate remaining compile time `error-pattern`s to line annotations when possible There's a number of cases in which `error-pattern` is still necessary even for compile time checking. - It checks something that compiler writes directly into stderr as text, and not to the structured json output. This includes some stuff reported during compiler panics, and also diagnostics that happen very early, for example when parsing the command line. - It checks something that exists only in the full rendered diagnostic test, but not in its structured components, for example code fragments or output of `-Ztrack-diagnostics`. (The latter can probably be converted to structured form though.) This is continuation of https://github.com/rust-lang/rust/pull/139137. r? `@jieyouxu` |

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.
Why Rust?
-
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).
