Add debug info tests for range, fix-sized array, and cell types
This PR add several debug info tests to guarantee that the displays of fixed sized arrays, range types, cell types, threads, locks, and mutexes in CDB are correct.
It also updates CDB tests for slices in pretty-std.rs after string visualization in WinDbg is fixed by this PR: #81898.
Fix ICE with `-Zunpretty=hir,typed`
This PR fixes#82328. The `-Zunpretty=hir,typed` pretty-printer maintains an `Option` with type-checking results and sets the `Option` to `Some` when entering a body. However, this leads to an ICE if an expression occurs in a function signature (i.e. outside of a body), such as `128` in
```rust
fn foo(-128..=127: i8) {}
```
This PR fixes the ICE by checking (if necessary) whether the expression's owner has a body, and retrieving type-checking results for that on the fly.
Allow loading of llvm plugins on nightly
Based on a discussion in #82734 / with `@wsmoses.`
Mainly moves [this](0149bc4e7e) behind a -Z flag, so it can only be used on nightly,
as requested by `@nagisa` in https://github.com/rust-lang/rust/issues/82734#issuecomment-835863940
This change allows loading of llvm plugins like Enzyme.
Right now it also requires a shared library LLVM build of rustc for symbol resolution.
```rust
// test.rs
extern { fn __enzyme_autodiff(_: usize, ...) -> f64; }
fn square(x : f64) -> f64 {
return x * x;
}
fn main() {
unsafe {
println!("Hello, world {} {}!", square(3.0), __enzyme_autodiff(square as usize, 3.0));
}
}
```
```
./rustc test.rs -Z llvm-plugins="./LLVMEnzyme-12.so" -C passes="enzyme"
./test
Hello, world 9 6!
```
I will try to figure out how to simplify the usage and get this into stable in a later iteration,
but having this on nightly will already help testing further steps.
rustdoc: Render `<Self as X>::Y` type casts properly across crate bounds
My last PR that introduced the type casting did not work for cross-crate re-exported traits, which is fixed in this PR.
Fully resolves#85454
Update array_into_iter lint for 1.53 and edition changes.
This updates the array_into_iter lint for Rust 1.53 and the edition changes.

Properly render HRTBs
```rust
pub fn test<T>()
where
for<'a> &'a T: Iterator,
{}
```
This will now render properly including the `for<'a>`
I do not know if this covers all cases, it only covers everything that I could think of that includes `for` and lifetimes in where bounds.
Also someone need to mentor me on how to add a proper rustdoc test for this.
Resolves#78482
Use HTTPS links where possible
While looking at #86583, I wondered how many other (insecure) HTTP links were in `rustc`. This changes most other `http` links to `https`. While most of the links are in comments or documentation, there are a few other HTTP links that are used by CI that are changed to HTTPS.
Notes:
- I didn't change any to or in licences
- Some links don't support HTTPS :(
- Some `http` links were dead, in those cases I upgraded them to their new places (all of which used HTTPS)
Check that `#[cmse_nonsecure_entry]` is applied to a function definition
This PR fixes#83475. The compiler currently neglects to check whether `#[cmse_nonsecure_entry]` is applied to a function (and not, say, a struct) definition, leading to an ICE later on when the type checker attempts to retrieve the function signature. I have fixed this problem by adding an appropriate check to the `check_attr` pass, so that an error is reported instead of an ICE.

Use `#[non_exhaustive]` where appropriate
Due to the std/alloc split, it is not possible to make `alloc::collections::TryReserveError::AllocError` non-exhaustive without having an unstable, doc-hidden method to construct (which negates the benefits from `#[non_exhaustive]`).

Change how edition based future compatibility warnings are handled
This fixes https://github.com/rust-lang/rust/issues/85894 by updating how future compatibility lints work. This makes it more apparent that future compatibility warnings can happen for several different reasons.
For now `FutureCompatibilityReasons` are limited to three reasons, but we can easily add more.
This also updates the generated warning for FCW's that signal code that will error in a future edition. This makes the diagnostics between FCWs at edition boundaries more distinct from those not happening at an edition boundary.

Add `BuildHasher::hash_one` as unstable
Inspired by https://github.com/rust-lang/rust/pull/86140/files#diff-246941135168fbc44fce120385ee9c3156e08a1c3e2697985b56dcb8d728eedeR2416, where I wanted to write a quick test for a `Hash` implementation and it took more of a dance than I'd hoped.
It looks like this would be handy in hashtable implementations, too -- a quick look at hashbrown found two places where it needs to do the same dance:
6302512a8a/src/map.rs (L247-L270)
I wanted to get a "seems plausible" from a libs member before making a tracking issue, so random-sampling the intersection of highfive and governance gave me...

(As always, bikeshed away! And let me know if I missed something obvious again that I should have used instead.)
Don't lint :pat when re-parsing a macro from another crate.
`compile_macro` is used both when compiling the original definition in the crate that defines it, and to compile the macro when loading it when compiling a crate that uses it. We should only emit lints in the first case.
This adds a `is_definition: bool` to pass this information in, so we don't warn about things that only concern the definition site.
Fixes#86567
