const_refs_to_static test and cleanup
r? ``@RalfJung``
test the existing behaviour of adt_const_params combined with const_refs_to_static.
also remove a dead error variant about consts referring to statics
Consistently use subtyping in method resolution
fixes#126062
An earlier version of this PR modified how we compute variance, but the root cause was an inconsistency between the usage of `eq` and `sub`, where we assumed that the latter passing implies the former will pass.

Convert a `span_bug` to a `span_delayed_bug`.
PR #121208 converted this from a `span_delayed_bug` to a `span_bug` because nothing in the test suite caused execution to hit this path. But now fuzzing has found a test case that does hit it. So this commit converts it back to `span_delayed_bug` and adds the relevant test.
Fixes#126385.

Make suggestion to change `Fn` to `FnMut` work with methods as well
Fixes#125325
The issue occurred because the code that emitted the suggestion to change `Fn` to `FnMut` worked only for function calls and not method calls. This PR makes it work with methods as well.
More preparation for new trait solver uplifting
Getting closer to being able to uplift the whole solver 🙏
Each commit should be self-justifying.

coverage: Several small improvements to graph code
This PR combines a few small improvements to coverage graph handling code:
- Remove some low-value implementation tests that were getting in the way of other changes.
- Clean up `pub` visibility.
- Flatten some code using let-else.
- Prefer `.copied()` over `.cloned()`.

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.
Add codegen test for `Request::provide_*`
Codegen before & after https://github.com/rust-lang/rust/pull/126242: https://gist.github.com/slanterns/3789ee36f59ed834e1a6bd4677b68ed4.
Also adjust an outdated comment since `tag_id` is no longer attached to `TaggedOption` via `Erased`, but stored next to it in `Tagged` under the new implementation.
My first time writing FileCheck xD. Correct me if there is anything that should be amended.

export std::os::fd module on HermitOS
The HermitOS' IO interface is similiar to Unix. Consequently, this PR synchronize the FD implementation between both.

doc: Added commas where needed

Resolve elided lifetimes in assoc const to static if no other lifetimes are in scope
Implements the change to elided lifetime resolution in *associated consts* subject to FCP here: https://github.com/rust-lang/rust/issues/125190#issue-2301532282
Specifically, walk the enclosing lifetime ribs in an associated const, and if we find no other lifetimes, then resolve to `'static`.
Also make it work for traits, but don't lint -- just give a hard error in that case.
`boxed_slice_into_iter`: tiny doc correction
`CURRENT_RUSTC_VERSION` isn't flexible enough for this, so it got replaced by 1.80.0 instead of 1.79.0 in #126273 :/
Remove unused `llvm_readobj.rs` in `run-make-support`
`llvm_readobj.rs` seems unused from the migration to `llvm.rs` in #125165.
Also, `llvm.rs` was missing the drop bombs (#125752) in `llvm_readobj.rs`.
Part of #121876.
r? `@jieyouxu`
Honor collapse_debuginfo for statics.
fixes#126363

rustc_span: Minor improvements
Introduce `{IndexNewtype,SyntaxContext}::from_u16` for convenience because small indices are sometimes encoded as `u16`.
Use `SpanData::span` instead of `Span::new` where appropriate.
Add a clarifying comment about decoding span parents.
