bump strip-ansi-escapes
This bumps `strip-ansi-escapes` to remove arrayvec from it's deps (https://github.com/luser/strip-ansi-escapes/pull/8)
Should Cargo.lock be commited too to track it's working state?
changelog: none
ast: Standardize visiting order
Order: ID, attributes, inner nodes in source order if possible, tokens, span.
Also always use exhaustive matching in visiting infra, and visit some discovered missing nodes.
Unlike https://github.com/rust-lang/rust/pull/125741 this shouldn't affect anything serious like `macro_rules` scopes.
Fix doc_markdown DevOps false positive
This fixes an issue where the word "DevOps" ends up as a false positive for the `doc_markdown` lint.
In a doc comment like this
```rust
/// Call the Azure DevOps REST API.
pub fn example() {}
```
the word "DevOps" is highlighted as something which should be in backticks.
```
warning: item in documentation is missing backticks
--> src/lib.rs:1:20
|
1 | /// Call the Azure DevOps REST API.
| ^^^^^^

```
This could be overriden with the `doc-valid-idents` configuration parameter as noted by the [documentation](https://rust-lang.github.io/rust-clippy/master/index.html#/doc_markdown), but I believe the word "DevOps" is sufficiently common to belong alongside exceptions like "GitHub" and "GitLab".

rustdoc: use current stage if download-rustc enabled
When using download-rustc, using stage 1 rustdoc results in the wrong librustc_driver being used.
```sh
$ ./build/host/stage1/bin/rustdoc --version
./build/host/stage1/bin/rustdoc: error while loading shared libraries: librustc_driver-7ff02ed05016d515.so: cannot open shared object file: No such file or directory
```
This change fixes that by not cutting the stage if download-rustc is enabled.
Remove `__rust_force_expr`.
This was added (with a different name) to improve an error message. It is no longer needed -- removing it changes the error message, but overall I think the new message is no worse:
- the mention of `#` in the first line is a little worse,
- but the extra context makes it very clear what the problem is, perhaps even clearer than the old message,
- and the removal of the note about the `expr` fragment (an internal detail of `__rust_force_expr`) is an improvement.
Overall I think the error is quite clear and still far better than the old message that prompted #61933, which didn't even mention patterns.
The motivation for this is #124141, which will cause pasted metavariables to be tokenized and reparsed instead of the AST node being cached. This change in behaviour occasionally has a non-zero perf cost, and `__rust_force_expr` causes the tokenize/reparse step to occur twice. Removing `__rust_force_expr` greatly reduces the extra overhead for the `deep-vector` benchmark.

coverage: Make `#[coverage(..)]` apply recursively to nested functions
This PR makes the (currently-unstable) `#[coverage(off)]` and `#[coverage(on)]` attributes apply recursively to all nested functions/closures, instead of just the function they are directly attached to.
Those attributes can now also be applied to modules and to impl/impl-trait blocks, where they have no direct effect, but will be inherited by all enclosed functions/closures/methods that don't override the inherited value.

Fixes for 32-bit SPARC on Linux
This PR fixes a number of issues which previously prevented `rustc` from being built
successfully for 32-bit SPARC using the `sparc-unknown-linux-gnu` triplet.
In particular, it adds linking against `libatomic` where necessary, uses portable `AtomicU64`
for `rustc_data_structures` and rewrites the spec for `sparc_unknown_linux_gnu` to use
`TargetOptions` and replaces the previously used `-mv8plus` with the more portable
`-mcpu=v9 -m32`.
To make `rustc` build successfully, support for 32-bit SPARC needs to be added to the `object`
crate as well as the `nix` crate which I will be sending out later as well.

patch `rust-lld` and `ld.lld` on NixOS
When `rustc` uses its self-contained lld, we also need to patch `rust-lld` and `ld.lld`.
The `rpath` for `rust-lld` is `$ORIGIN/../../../:$ORIGIN/../lib`, so I use `--add-rpath` instead of `--set-rpath`, which should be easier to maintain.
I also changed `src/bootstrap/src/core/download.rs`, even this doesn't fix any known issues.
For the `lld-wrapper.sh` of lld, refer to: https://github.com/rust-lang/rustc-dev-guide/pull/1999.
Id, attributes, inner nodes in source order if possible, tokens, span.

Remove more `PtrToPtr` casts in GVN
This addresses two things I noticed in MIR:
1. `NonNull::<T>::eq` does `(a as *mut T) == (b as *mut T)`, but it could just compare the `*const T`s, so this removes `PtrToPtr` casts that are on both sides of a pointer comparison, so long as they're not fat-to-thin casts.
2. `NonNull::<T>::addr` does `transmute::<_, usize>(p as *const ())`, but so long as `T: Thin` that cast doesn't do anything, and thus we can directly transmute the `*const T` instead.

Add more constants, functions, and tests for `f16` and `f128`
This adds everything that was in some way blocked on const eval, since https://github.com/rust-lang/rust/pull/126429 landed. There is a lot of `cfg(bootstrap)` since that is a fairly recent change.
`f128` tests are disabled on everything except x86_64 and Linux aarch64, which are two platforms I know have "good" support for these types - meaning basic math symbols are available and LLVM doesn't hit selection crashes. `f16` tests are enabled on almost everything except for known LLVM crashes. Doctests are only enabled on x86_64.

fix broken build cache caused by rustdoc builds
Currently rustdoc breaks the build cache (due to having different rustflags) when building rustdoc before building another tool (e.g., `x test miri && x test rustdoc && x test miri`).
This change fixes that by moving `on-broken-pipe` into `prepare_cargo_tool` so it is set for all tools.

Bump black, ruff and platformdirs
Mainly because I encountered the following error, and we have no reason to prevent our upgrade.
```
ERROR: pip's dependency resolver does not currently take into account all the packages that are installed.
This behaviour is the source of the following dependency conflicts.
virtualenv 20.25.3 requires platformdirs<5,>=3.9.1, but you have platformdirs 3.6.0 which is incompatible.
```

Don't ICE during RPITIT refinement checking for resolution errors after normalization
#126670 shows a case where resolution errors after normalization can happen during RPITIT refinement checking. Our tests didn't reach this path before, and we explicitly ICEd until we had a test. We can now delay a bug since we're sure it is reachable and have the test from the isue.
The comment I added likely still needs more expert wordsmithing.

miri: make sure we can find link_section statics even for the local crate
Miri needs some way to iterate all the exported functions and "used" statics of all crates. For dependency crates, this already works fine since we can overwrite the query resonsible for computing `exported_symbols`, but it turns out for local binary crates this does not work: for binaries, `reachable_set` skips a lot of its logic and only checks `contains_extern_indicator()` and `RUSTC_STD_INTERNAL_SYMBOL`. Other flags like `CodegenFnAttrFlags::USED` are entirely ignored.
This PR proposes to use the same check, `has_custom_linkage`, in binaries that we already use to drive the main workqueue of the reachability recursive traversal. I have no idea why binaries used a slightly different check that ignores `USED` -- was that deliberate or does it just not matter most of the time?

fix Drop items getting leaked in Filter::next_chunk
The optimization only makes sense for non-drop elements anyway. Use the default implementation for items that are Drop instead.
It also simplifies the implementation.

tracking issue #98326
Fix a span in `parse_ty_bare_fn`.
It currently goes one token too far.
Example: line 259 of `tests/ui/abi/compatibility.rs`:
```
test_abi_compatible!(fn_fn, fn(), fn(i32) -> i32);
```
This commit changes the span for the second element from `fn(),` to `fn()`, i.e. removes the extraneous comma.
This doesn't affect any tests. I found it while debugging some other code. Not a big deal but an easy fix so I figure it worth doing.
