rustdoc: update to pulldown-cmark 0.11
r? rustdoc
This pull request updates rustdoc to the latest version of pulldown-cmark. Along with adding new markdown extensions (which this PR doesn't enable), the new pulldown-cmark version also fixes a large number of bugs. Because all text files successfully parse as markdown, these bugfixes change the output, which can break people's existing docs.
A crater run, https://github.com/rust-lang/rust/pull/121659, has already been run for this change.
The first commit upgrades and fixes rustdoc. The second commit adds a lint for the footnote and block quote parser changes, which break the largest numbers of docs in the Crater run. The strikethrough change was mitigated in pulldown-cmark itself.

Disable rmake test rustdoc-io-error on riscv64gc-gnu
In https://github.com/rust-lang/rust/pull/126917 we disabled `inaccessible-temp-dir` on `riscv64gc-gnu` because the container runs the build as `root` (just like the `armhf-gnu` builds). Tests creating an inaccessible test directory are not possible, since `root` can always touch those directories.
https://github.com/rust-lang/rust/blob/553a69030e5a086eb3841d020db8c9c463948c72/src/ci/docker/host-x86_64/disabled/riscv64gc-gnu/Dockerfile#L99
This means the tests are run as `root`. As `root`, it's perfectly normal and reasonable to violate permission checks this way:
```bash
$ sudo mkdir scratch
$ sudo chmod o-w scratch
$ sudo mkdir scratch/backs
$
```
Because of this, this PR makes the test ignored on `riscv64gc` (just like on `armhf-gnu`) for now.
As an alternative, I believe the best long-term strategy would be to not run the tests as `root` for this job. Some preliminary exploration was done in https://github.com/rust-lang/rust/pull/126917#issuecomment-2189933970, however that appears a larger lift.
## Testing
> [!NOTE]
> `riscv64gc-unknown-linux-gnu` is a [**Tier 2 with Host Tools** platform](https://doc.rust-lang.org/beta/rustc/platform-support.html), all tests may not necessarily pass! This change should only ignore `inaccessible-temp-dir` and not affect other tests.
You can test out the job locally:
```sh
DEPLOY=1 ./src/ci/docker/run.sh riscv64gc-gnu
```

Fix incorrect suggestion for extra argument with a type error
Fixes #126246
I tried to fix it in the `find_errors` of ArgMatrix, but seems it's hard to avoid breaking some other test cases.
The root cause is we eliminate the first argument even with a type error at here:
https://github.com/rust-lang/rust/blob/6292b2af620dbd771ebb687c3a93c69ba8f97268/compiler/rustc_hir_typeck/src/fn_ctxt/checks.rs#L664
So the left argument is always treated as extra one.
But if there is already a type error, an error message will be generated firstly, which make this issue a trivial one.

Add parse fail test using safe trait/impl trait
Added 2 more tests to be sure that nothing weird happens using `safe` on items.
Needed to do this in separate tests as they give parsing errors.

Remove global error count checks from typeck
Some of these are not reachable anymore, others can now rely on information local to the current typeck run. One check was actually invalid, because it was relying on wfcheck running before typeck, which is not guaranteed in the query system and usually easy to create ICEing examples for via const eval (which runs typeck before wfcheck)

linker: Link dylib crates by path
Linkers seem to support linking dynamic libraries by path.
Not sure why the previous scheme with splitting the path into a directory (passed with `-L`) and a name (passed with `-l`) was used (upd: likely due to https://github.com/rust-lang/rust/pull/126094#issuecomment-2155063414).
When we split a library path `some/dir/libfoo.so` into `-L some/dir` and `-l foo` we add `some/dir` to search directories for *all* libraries looked up by the linker, not just `foo`, and `foo` is also looked up in *all* search directories not just `some/dir`.
Technically we may find some unintended libraries this way.
Therefore linking dylibs via a full path is both simpler and more reliable.
It also makes the set of search directories more easily reproducible when we need to lookup some native library manually (like in https://github.com/rust-lang/rust/pull/123436).

Re-implement a type-size based limit
r? lcnr
This PR reintroduces the type length limit added in #37789, which was accidentally made practically useless by the caching changes to `Ty::walk` in #72412, which caused the `walk` function to no longer walk over identical elements.
Hitting this length limit is not fatal unless we are in codegen -- so it shouldn't affect passes like the mir inliner which creates potentially very large types (which we observed, for example, when the new trait solver compiles `itertools` in `--release` mode).
This also increases the type length limit from `1048576 == 2 ** 20` to `2 ** 24`, which covers all of the code that can be reached with craterbot-check. Individual crates can increase the length limit further if desired.
Perf regression is mild and I think we should accept it -- reinstating this limit is important for the new trait solver and to make sure we don't accidentally hit more type-size related regressions in the future.

Disable rmake test `inaccessible-temp-dir` on riscv64
In https://github.com/rust-lang/rust/pull/126279 the `inaccessible-temp-dir` test was moved to rmake, I followed up with a 'fix' derived from https://github.com/rust-lang/rust/pull/126355 in https://github.com/rust-lang/rust/pull/126707.
That 'fix' was misguided and hiding the true issue of the linker being incorrect for `riscv64gc-unknown-linux-gnu` (addressed in https://github.com/rust-lang/rust/pull/126916).
Unfortunately, even with the linker fixed, this test doesn't work. I asked myself why this appeared to work on other platforms and investigated why. Both the containers for `armhf-gnu` and `riscv64gc` run their tests as `root` and have `NO_CHANGE_USER` set:
https://github.com/rust-lang/rust/blob/553a69030e5a086eb3841d020db8c9c463948c72/src/ci/docker/host-x86_64/disabled/riscv64gc-gnu/Dockerfile#L99
This means the tests are run as `root`. As `root`, it's perfectly normal and reasonable to violate permission checks this way:
```bash
$ sudo mkdir scratch
$ sudo chmod o-w scratch
$ sudo mkdir scratch/backs
$
```
Because of this, this PR makes the test ignored on `riscv64gc` for now.
As an alternative, I believe the best long-term strategy would be to not run the tests as `root` for this job.

Actually report normalization-based type errors correctly for alias-relate obligations in new solver
We have some special casing to report type mismatch errors that come from projection predicates, but we don't do that for alias-relate obligations. This PR implements that. There's a bit of code duplication, but 🤷
Best reviewed without whitespace.

Stabilize `hint::assert_unchecked`
Make the following API stable, including const:
```rust

This PR also reworks some of the documentation and adds an example.
Tracking issue: https://github.com/rust-lang/rust/issues/119131
FCP: https://github.com/rust-lang/rust/issues/119131#issuecomment-1906394087. The docs update should resolve the remaining concern.

Check alias args for WF even if they have escaping bound vars
#### What
This PR stops skipping arguments of aliases if they have escaping bound vars, instead recursing into them and only discarding the resulting obligations referencing bounds vars.
#### An example:
From the test:
```
trait Trait {
type Gat<U: ?Sized>;
}
fn test<T>(f: for<'a> fn(<&'a T as Trait>::Gat<&'a [str]>)) where for<'a> &'a T: Trait {}
//~^ ERROR the size for values of type `[()]` cannot be known at compilation time
fn main() {}
```
We now prove that `str: Sized` in order for `&'a [str]` to be well-formed. We were previously unconditionally skipping over `&'a [str]` as it referenced a buond variable. We now recurse into it and instead only discard the `[str]: 'a` obligation because of the escaping bound vars.
#### Why?
This is a change that improves consistency about proving well-formedness earlier in the pipeline, which is necessary for future work on where-bounds in binders and correctly handling higher-ranked implied bounds. I don't expect this to fix any unsoundness.
#### What doesn't it fix?
Specifically, this doesn't check projection predicates' components are well-formed, because there are too many regressions: https://github.com/rust-lang/rust/pull/123737#issuecomment-2052198478

Use the aligned size for alloca at args/ret when the pass mode is cast
Fixes #75839. Fixes #121028.
The `load` and `store` instructions in LLVM access the aligned size. For example, `load { i64, i32 }` accesses 16 bytes on x86_64: https://alive2.llvm.org/ce/z/n8CHAp.
BTW, this example is expected to be optimized to immediate UB by Alive2: https://rust.godbolt.org/z/b7xK7hv1c and https://alive2.llvm.org/ce/z/vZDtZH.

Fix `FnMut::call_mut`/`Fn::call` shim for async closures that capture references
I adjusted async closures to be able to implement `Fn` and `FnMut` *even if* they capture references, as long as those references did not need to borrow data from the closure captures themselves. See #125259.
However, when I did this, I didn't actually relax an assertion in the `build_construct_coroutine_by_move_shim` shim code, which builds the `Fn`/`FnMut`/`FnOnce` implementations for async closures. Therefore, if we actually tried to *call* `FnMut`/`Fn` on async closures, it would ICE.
This PR adjusts this assertion to ensure that we only capture immutable references in closures if they implement `Fn`/`FnMut`. It also adds a bunch of tests and makes more of the async-closure tests into `build-pass` since we often care about these tests actually generating the right closure shims and stuff. I think it might be excessive to *always* use build-pass here, but 🤷 it's not that big of a deal.

Parenthesize break values containing leading label
The AST pretty printer previously produced invalid syntax in the case of `break` expressions with a value that begins with a loop or block label.
```rust
macro_rules! expr {
($e:expr) => {
$e
};
}
fn main() {
loop {
break expr!('a: loop { break 'a 1; } + 1);
};
}
```
`rustc -Zunpretty=expanded main.rs `:
```console
#![feature(prelude_import)]
#![no_std]
#[prelude_import]
use ::std::prelude::rust_2015::*;
#[macro_use]
extern crate std;
macro_rules! expr { ($e:expr) => { $e }; }
fn main() { loop { break 'a: loop { break 'a 1; } + 1; }; }
```
The expanded code is not valid Rust syntax. Printing invalid syntax is bad because it blocks `cargo expand` from being able to format the output as Rust syntax using rustfmt.
```console
error: parentheses are required around this expression to avoid confusion with a labeled break expression
--> <anon>:9:26

9 | fn main() { loop { break 'a: loop { break 'a 1; } + 1; }; }

help: wrap the expression in parentheses
|
9 | fn main() { loop { break ('a: loop { break 'a 1; }) + 1; }; }

```
This PR updates the AST pretty-printer to insert parentheses around the value of a `break` expression as required to avoid this edge case.
