Rollup merge of #147623 - Zalathar:clear-mixed, r=nnethercote

Clear `ChunkedBitSet` without reallocating

There doesn't appear to be any reason to clear a ChunkedBitSet via its constructor (which allocates a new list of chunks), when we could just fill the existing allocation with `Chunk::Zeros` instead.

For comparison, the `insert_all` impl added by the same PR (rust-lang/rust#93984) does the simple thing here and just overwrites every chunk with `Chunk::Ones`.

(That fill was then made somewhat easier by rust-lang/rust#145480, which removes the chunk size from all-zero/all-one chunks.)

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).
