Move `DebuggerCommands` and `check_debugger_output` to a separate module
Work towards #89475.
As part of this move, the public functions were changed to return `Result`. This is so that the error handling that initially took `&self: TestCx` can still use that `TestCx`.
Cleanup src/test/ui/{simd,simd-intrinsic}
Initial motivation was to simplify a huge macro expansion using a tuple, since we can just use an array in `#[repr(simd)]` now for the same result. But also, several tests were going unnoticed during development of SIMD intrinsics because people kept looking in the wrong directory, and many are basically run-pass vs. build-fail versions of the same tests, so let's keep them close together and simplify their names, so they're easier to sift through.
Rustc was incorrectly reading the value of `RUSTC_LOG` as the
environment vairable with the logging configuration, rather than the
logging configuration itself.
Cfg hide no_global_oom_handling and no_fp_fmt_parse
These are unstable sysroot customisation cfg options that only projects building their own sysroot will use (e.g. Rust-for-linux). Most users shouldn't care. `no_global_oom_handling` can be especially annoying since it's applied on many commonly used alloc crate methods (e.g. `Box::new`, `Vec::push`).

Don't rebuild GUI test crates every time you run test src/test/rustdoc-gui
This method has multiple advantages:
* It'll completely remove the rustdoc-GUI test doc folder if rustdoc was updated
* It'll rebuild GUI test crates only they have been updated
All in all, it's quite convenient! (even more with https://github.com/rust-lang/rust/pull/88816)

docs: `std:#️⃣:Hash` should ensure prefix-free data
Attempt to synthesize the discussion in #89429 into a suggestion regarding `Hash` implementations (not a hard requirement).
Closes#89429.
Improve docs for int_log
* Clarify rounding.
* Avoid "wrapping" wording.
* Omit wrong claim on 0 only being returned in error cases.
* Typo fix for one_less_than_next_power_of_two.
Show detailed expected/found types in error message when trait paths are the same
Fixes#65230.
### Issue solved by this PR
```rust
trait T {
type U;
fn f(&self) -> Self::U;
}
struct X<'a>(&'a mut i32);
impl<'a> T for X<'a> {
type U = &'a i32;
fn f(&self) -> Self::U {
self.0
}
}
fn main() {}
```
Compiler generates the following note:
```
note: ...so that the types are compatible
--> test.rs:10:28
|
10 | fn f(&self) -> Self::U {
| ____________________________^
11 | | self.0
12 | | }
| |_____^
= note: expected `T`
found `T`
```
This note is not useful since the expected type and the found type are the same.
### How this PR solve the issue
When the expected type and the found type are exactly the same in string representation, the note falls back to the detailed string representation of trait ref:
```
note: ...so that the types are compatible
--> test.rs:10:28
|
10 | fn f(&self) -> Self::U {
| ____________________________^
11 | | self.0
12 | | }
| |_____^
= note: expected `<X<'a> as T>`
found `<X<'_> as T>`
```
So that a user can notice what was different between the expected one and the found one.
Add new tier-3 target: armv7-unknown-linux-uclibceabihf
This change adds a new tier-3 target: armv7-unknown-linux-uclibceabihf
This target is primarily used in embedded linux devices where system resources are slim and glibc is deemed too heavyweight. Cross compilation C toolchains are available [here](https://toolchains.bootlin.com/) or via [buildroot](https://buildroot.org).
The change is based largely on a previous PR #79380 with a few minor modifications. The author of that PR was unable to push the PR forward, and graciously allowed me to take it over.
Per the [target tier 3 policy](https://github.com/rust-lang/rfcs/blob/master/text/2803-target-tier-policy.md), I volunteer to be the "target maintainer".
This is my first PR to Rust itself, so I apologize if I've missed things!
Move top part of print_item to Tera templates
Part of #84419.
This moves the first line of each item page (E.g. `Struct foo::Bar .... 1.0.0 [-][src]` into a Tera template.
I also moved template initialization into its own module and added a small macro to reduce duplication and opportunity for errors.
CI: Use mirror for libisl downloads for more docker dist builds
http://isl.gforge.inria.fr fell from the net a couple of days ago. It hosts libisl source tarballs required by crosstool-ng, which we use for our docker dist cross-compilation builds. Some of the affected builds were already fixed in #89599.
This PR sets a mirror URL for the other builds requiring libisl-0.14. They use an older version of crosstool-ng (1.22.0), which has only one mirror setting for all downloads.
