It prevents a full rebuild of stage 1 compiler when issuing "x.py test" with rust.lto != thin-local in config.toml.
Two optimizations for the function signature search: * Instead of using JSON arrays, like `[1,20]`, it uses VLQ hex with no commas, like `[aAd]`. * This also adds backrefs: if you have more than one function with exactly the same signature, it'll not only store it once, it'll *decode* it once, and store in the typeIdMap only once.

This draws a clear distinction between the fields/methods that are needed by initial span extraction and preprocessing, and those that are needed by the main "refinement" loop.
The struct itself is already non-public, so having public fields doesn't achieve anything.
nightly feature (Using this attribute still requires a nightly feature, this just enables that this feature does not need to be enabled on the child crate as well)
`#[diagnostic::on_unimplemented]` This commit replaces those `#[rustc_on_unimplemented]` attributes with their equivalent `#[diagnostic::on_unimplemented]` where this is supported (So no filter or any extended option)
the corresponding feature.
…tinem coverage: Hoist some complex code out of the main span refinement loop The span refinement loop in `spans.rs` takes the spans that have been extracted from MIR, and modifies them to produce more helpful output in coverage reports. It is also one of the most complicated pieces of code in the coverage instrumentor. It has an abundance of moving pieces that make it difficult to understand, and most attempts to modify it end up accidentally changing its behaviour in unacceptable ways. This PR nevertheless tries to make a dent in it by hoisting two pieces of special-case logic out of the main loop, and into separate preprocessing passes. Coverage tests show that the resulting mappings are *almost* identical, with all known differences being unimportant. This should hopefully unlock further simplifications to the refinement loop, since it now has fewer edge cases to worry about.
…in_stdlib, r=compiler-errors Use diagnostic namespace in stdlib This required a minor fix to have the diagnostics shown in third party crates when the `diagnostic_namespace` feature is not enabled. See rust-lang@5d63f5d for details. I've opted for having a single PR for both changes as it's really not that much code. If it is required it should be easy to split up the change into several PR's. r? `@compiler-errors`

…r-errors remove duplicate test This was added in rust-lang@ace6fc3 where overflowing-rsh-6 differed from overflowing-rsh-5 in a feature gate, but the feature has since been stabilized, making the tests 100% identical. Most of these tests in numbers-arithmetic could be put into one file rather than having so many files that all test the same lint... but it doesn't seem worth the effort. After rust-lang#119432 we might be able to remove most of them entirely as they will be covered by the new tests added there.
…le-error, r=cjgillot fix cyle error when suggesting to use associated function instead of constructor Fixesrust-lang#119625. The first commit fixes the infinite recursion and makes the cycle error actually show up. We do this by making the `Display` for `ty::Instance` impl respect `with_no_queries` so that it can be used in query descriptions. The second commit fixes the cycle error `resolver_for_lowering` -> `normalize` -> `resolve_instance` (for evaluating const) -> `lang_items` (for `drop_in_place`) -> `resolver_for_lowering` (for collecting lang items). We do this by simply skipping the suggestion when encountering an unnormalized type.
