coverage: Arrange span extraction/refinement as a series of passes The old code for extracting/refining coverage spans from MIR has been dismantled and split up into several passes (e.g. see #126294), but because this was done incrementally, the resulting code is disorganised. This PR addresses that by moving the main control-flow into a single function (`coverage::spans::extract_refined_covspans`) that more clearly shows the process as a series of separate steps, most delegated to helper functions in the same file. This should make it easier to understand and modify the refinement process. It also means that submodule `from_mir` is now only concerned with the details of extracting relevant spans from the various kinds of MIR statement/terminator. There should be no change to the resulting coverage maps, as demonstrated by the lack of changes to tests. |

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).
