Rollup merge of #151696 - amandasystems:scc-annotations-update, r=lcnr

Borrowck: Simplify SCC annotation computation, placeholder rewriting

This change backports some changes from the now abandoned rust-lang/rust#142623.

Notably, it simplifies the `PlaceholderReachability` `enum` by replacing the case when no placeholders were reached with a standard `Option::None`.

It also rewrites the API for `scc::Annotations` to be update-mut rather than a more Functional programming style. This showed some slight performance impact in early tests of the PR and definitely makes the implementation simpler.

This probably wants a perf run just for good measure.

Website | Getting started | Learn | Documentation | Contributing

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).
