Move methods from `Map` to `TyCtxt`, part 5.
This eliminates all methods on `Map`. Actually removing `Map` will occur in a follow-up PR.
A follow-up to #137504.

Remove cjgillot from automated review assignment
As discussed [on Zulip](https://rust-lang.zulipchat.com/#narrow/channel/131828-t-compiler/topic/Review.20for.20.23137465/with/508540539).
To be clear, this is not a value judgement, it's just a way to improve our fairness when assigning reviews, trying to find a balance between leaving time to Rust contributors review on their terms and availability and avoid having PRs waiting for too long.
> [!IMPORTANT]
> This is not a final decision! Rust contributors are free to re-add themselves back to the active review rotation (if they feel like it) once they have more availability.

`for_each_assignment_mut` can skip assignment statements with side effects,
which can result in some assignment statements retrieving outdated value.
For example, it may skip a dereference assignment statement.
Various local trait item iteration cleanups
Adding a trait impl for `Foo` unconditionally affected all queries that are interested in a completely independent trait `Bar`. Perf has no effect on this. We probably don't have a good perf test for this tho.
r? `@compiler-errors`
I am unsure about https://github.com/rust-lang/rust/pull/139018/commits/9d05efb66f7b599eeacb5d2456f844fe4768e865 as it doesn't improve anything wrt incremental, because we still do all the checks for valid `Drop` impls, which subsequently will still invoke many queries and basically keep the depgraph the same.
I want to do
9549077a47/compiler/rustc_middle/src/ty/trait_def.rs (L141)
but would leave that to a follow-up PR, this one changes enough things as it is
`AstValidator` has several `with_*` methods, each one setting a field
that adjust how checking takes place for items within certain other
items. E.g. `with_in_trait_impl` is used to adjust the checking done on
items inside an `impl` item. Weirdly, the scopes used for most of the
`with_*` calls are very broad, and include things that aren't "inside"
the item, such as visibility, unsafety, and constness.
This commit minimizes the scope of these `with_*` calls so they only
apply to the things inside the item.

`@rustbot` modify labels: rollup
A bunch of span-related names in `AstValidator` don't end in `span`,
which goes against the usual naming conventions and makes the code
surprisingly hard to read. E.g. a name like `body` doesn't sound like
it's a span.
This commit adds `_span` suffixes.
move autodiff from EnzymeAD/Enzyme to our rust-lang/Enzyme soft-fork
In https://github.com/rust-lang/team/pull/1665 we decided to have a soft-fork of Enzyme, to be able to merge e.g. CI, docs, or cmake improvements if upstream is not interested in them. We don't intend to merge logic/code changes. It also seems generally preferable if we clone submodules from a rust-lang repo, instead of an external org. We don't build or checkout Enzyme yet by default, so this should be a safe rollup.
Tell rustfmt to use the 2024 edition in ./x.py fmt
Most crates in this repo have been moved to the 2024 edition already. This also allows removing a rustfmt exclusion for a cg_clif test.
Skip suggest impl or dyn when poly trait is not a real trait
Fixes#139174
When `poly_trait_ref` is not a real trait, we should stop suggesting `impl` and `dyn` to avoid false positives. 3 cases were added to the ui test.

In the first commit, I submitted the test and passed it. In the second commit, I modified the code and we can see the changes in the test.

coverage: Avoid splitting spans during span extraction/refinement
This PR removes or simplifies some of the steps involved in extracting coverage-relevant spans from MIR, and preparing them for use in coverage instrumentation metadata.
A common theme is that we now try harder to avoid modifying or combining spans in non-trivial ways, because those modifications present the most risk for weird behaviour or ICEs.
The main changes are:
- When extracting spans from MIR call terminators, try to restrict them to just the function name.
- Instead of splitting spans around “holes”, just discard any span that overlaps with a hole.
- Instead of splitting macro-invocation spans into two parts, truncate them to just the macro name and subsequent `!`.
---
This results in a lot of tiny changes to the spans that end up in coverage metadata, and a few changes to coverage reports. Judging by test snapshots, these changes appear to be quite minor in practice.
Do not mix normalized and unnormalized caller bounds when constructing param-env for `receiver_is_dispatchable`
See comments in code and in test I added.
