Continuing the work started in #136466.
Every method gains a `hir_` prefix, though for the ones that already
have a `par_` or `try_par_` prefix I added the `hir_` after that.
First of all, note that `Map` has three different relevant meanings.
- The `intravisit::Map` trait.
- The `map::Map` struct.
- The `NestedFilter::Map` associated type.
The `intravisit::Map` trait is impl'd twice.
- For `!`, where the methods are all unreachable.
- For `map::Map`, which gets HIR stuff from the `TyCtxt`.
As part of getting rid of `map::Map`, this commit changes `impl
intravisit::Map for map::Map` to `impl intravisit::Map for TyCtxt`. It's
fairly straightforward except various things are renamed, because the
existing names would no longer have made sense.
- `trait intravisit::Map` becomes `trait intravisit::HirTyCtxt`, so named
because it gets some HIR stuff from a `TyCtxt`.
- `NestedFilter::Map` assoc type becomes `NestedFilter::MaybeTyCtxt`,
because it's always `!` or `TyCtxt`.
- `Visitor::nested_visit_map` becomes `Visitor::maybe_tcx`.
I deliberately made the new trait and associated type names different to
avoid the old `type Map: Map` situation, which I found confusing. We now
have `type MaybeTyCtxt: HirTyCtxt`.
The end goal is to eliminate `Map` altogether.
I added a `hir_` prefix to all of them, that seemed simplest. The
exceptions are `module_items` which became `hir_module_free_items` because
there was already a `hir_module_items`, and `items` which became
`hir_free_items` for consistency with `hir_module_free_items`.
Rename rustc_middle::Ty::is_unsafe_ptr to is_raw_ptr
The wording unsafe pointer is less common and not mentioned in a lot of places, instead this is usually called a "raw pointer". For the sake of uniformity, we rename this method.
This came up during the review of
https://github.com/rust-lang/rust/pull/134424.

compiler: replace `ExternAbi::name` calls with formatters
Most of these just format the ABI string, so... just format ExternAbi? This makes it more consistent and less jank when we can do it.

Update bootstrap compiler and rustfmt
The rustfmt version we previously used formats things differently from what the latest nightly rustfmt does. This causes issues for subtrees that get formatted both in-tree and in their own repo. Updating the rustfmt used in-tree solves those issues. Also bumped the bootstrap compiler as the stage0 update command always updates both at the same
time.
Make empty-line-after an early clippy lint
r? ```@y21```
95% a refiling of https://github.com/rust-lang/rust-clippy/pull/13658 but for correctness it needed 2 extra methods in `rust_lint` which made it much easier to apply on `rust-lang/rust` than `rust-lang/rust-clippy`.
Commits have been thoroughly reviewed on `rust-lang/clippy already`. The last two review comments there (about using `Option` and popping for assoc items have been applied here.
this commit makes `deref_into_dyn_supertrait` lint allow-by-default,
removes future incompatibility (we finally live in a broken world), and
changes the wording in the documentation.
previously documentation erroneously said that it lints against *usage*
of the deref impl, while it actually (since 104742) lints on the impl
itself (oooops, my oversight, should have updated it 2+ years ago...)
Fix accidentally not emitting overflowing literals lints anymore in patterns
This was regressed in https://github.com/rust-lang/rust/pull/134228 (not in beta yet).
The issue was that previously we nested `hir::Expr` inside `hir::PatKind::Lit`, so it was linted by the expression code.
So now I've set it up for visitors to be able to directly visit literals and get all literals
Convert two `rustc_middle::lint` functions to `Span` methods.
`rustc_middle` is a huge crate and it's always good to move stuff out of it. There are lots of similar methods already on `Span`, so these two functions, `in_external_macro` and `is_from_async_await`, fit right in. The diff is big because `in_external_macro` is used a lot by clippy lints.

Compiler: Finalize dyn compatibility renaming
Update the Reference link to use the new URL fragment from https://github.com/rust-lang/reference/pull/1666 (this change has finally hit stable). Fixes a FIXME.
Follow-up to #130826.
Part of #130852.
~~Blocking it on #133372.~~ (merged)

Simplify and consolidate the way we handle construct `OutlivesEnvironment` for lexical region resolution
This is best reviewed commit-by-commit. I tried to consolidate the API for lexical region resolution *first*, then change the API when it was finally behind a single surface.

Use identifiers more in diagnostics code
This should make the diagnostics code slightly more correct when rendering idents in mixed crate edition situations. Kinda a no-op, but a cleanup regardless.

Make the wasm_c_abi future compat warning a hard error
This is the next step in getting rid of the broken C abi for wasm32-unknown-unknown.
The lint was made deny-by-default in https://github.com/rust-lang/rust/pull/129534 3 months ago. This still keeps the `-Zwasm-c-abi` flag set to `legacy` by default. It will be flipped in a future PR.

Improve check-cfg expected names diagnostic
This PR improves the check-cfg `allow-same-level` test by ~~normalizing it's output and by~~ adding more context to the test.
It also filters the well known cfgs from the `expected names are` note, as to reduce the size of the diagnostic. Users can still find the full list on the [rustc book](https://doc.rust-lang.org/nightly/rustc/check-cfg.html#well-known-names-and-values), which is reinforced for Cargo users by adding a note in the Cargo check-cfg specific section.
Fixes https://github.com/rust-lang/rust/issues/135995
