Remove unused dependencies from compiler crates
Various compiler crates have dependencies that they don't appear to use. I used some scripting to detect such dependencies, filtered them based on some manual review, and removed those that do indeed appear to be entirely unused.
Test cross-crate usage of `feature(const_trait_impl)`
This PR does two things:
- Fixes metadata not encoded properly for functions in const trait impls.
- Adds tests for using const trait impls cross-crate with the feature gate on the user crate either enabled or disabled.
AFAIK, this means we can now constify some trait impls in the standard library 🎉

Fix rustdoc query type filter
I realized while reviewing #86659 that the type filter was broken on search so I'd prefer it to get merged before merging #86659.

copy rust-lld as ld in dist
Fixes bug in https://github.com/rust-lang/rust/pull/85961. Linking seems to work for pure Rust projects, but not when a C library needs to be dynamically linked.
Check node kind to avoid ICE in `check_expr_return()`
This PR fixes#86721. The ICE described there is apparently due to a misunderstanding:
e98897e5dc/compiler/rustc_typeck/src/check/expr.rs (L684-L685)
Intuitively, one would think that calling `expect_item()` after `get_parent_item()` should succeed, but as it turns out, `get_parent_item()` can also return foreign, trait, and impl items as well as crates, whereas `expect_item()` specifically expects a `Node::Item`. I have therefore added an extra check to prevent this ICE.
Introduce -Zprofile-closures to evaluate the impact of 2229
This creates a CSV with name "closure_profile_XXXXX.csv", where the
variable part is the process id of the compiler.
To profile a cargo project you can run one of the following depending on
if you're compiling a library or a binary:
```
cargo +nightly rustc --lib -- -Zprofile-closures
cargo +nightly rustc --bin {binary_name} -- -Zprofile-closures
```

Fix boldness (put it back where needed)
I realized that I created a GUI test that wasn't run because it had ".rs" extension instead of ".goml" so I moved its content into `font-weight.goml` (since it was checking font weight).
Only include lint in future_incompatible lint group if not an edition lint
A follow up to #86330 - this only includes lints annotated with `FutureIncompatibleInfo` in the `future_incompatibile` lint group if the future compatibility is not tied to an edition.
We probably want to rename `FutureIncompatibleInfo` to something else since this type is now used to indicate future breakages of all kinds (even those that happen in editions). I'd prefer to do that in a separate PR though.

Change vtable memory representation to use tcx allocated allocations.
This fixes https://github.com/rust-lang/rust/issues/86324. However i suspect there's more to change before it can land.

Don't make `rustc_insignificant_dtor` feature gate
This isn't a feature gate, it's an attribute that is feature gated behind the `rustc_attrs` attribute. Closes#85680.
