Disable dead variant removal for `#[repr(C)]` enums. This prevents removing dead branches from a `#[repr(C)]` enum (they now get discriminants allocated as if they were inhabited). Implementation notes: ABI of something like ```rust #[repr(C)] enum Foo { Foo(!), } ``` is still `Uninhabited`, but its layout is now computed as if all the branches were inhabited. This seemed to me like a proper way to do it, especially given that ABI sanity check explicitly asserts that type-level uninhabitedness implies ABI uninhabitedness. This probably needs some sort of FCP (given that it changes `#[repr(C)]` layout, which is a stable guarantee), but I’m not sure how to call for one or which team is the most relevant.

README.md
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).
