Fix asm goto with outputs and move it to a separate feature gate Tracking issue: #119364 This PR addresses 3 aspects of asm goto with outputs: * Codegen is fixed. My initial implementation has an oversight which cause the output to be only stored in fallthrough path, but not in label blocks. * Outputs can now be used with `options(noreturn)` if a label block is given. * All of this is moved to a new feature gate, because we likely want to stabilise `asm_goto` before asm goto with outputs. `@rustbot` labels: +A-inline-assembly +F-asm |

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 integrate 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).
