Remove `<mbe::TokenTree as Clone>`
`mbe::TokenTree` doesn't really need to implement `Clone`, and getting rid of that impl leads to some speed-ups.

errors: lazily load fallback fluent bundle
Addresses (hopefully) https://github.com/rust-lang/rust/pull/95667#issuecomment-1094794087.
Loading the fallback bundle in compilation sessions that won't go on to emit any errors unnecessarily degrades compile time performance, so lazily create the Fluent bundle when it is first required.
r? `@ghost` (just for perf initially)
Update stdarch
library/stdarch bcbe0106...d215afe9 (7):
- Add the rdm target feature to the sqrdmlsh intrinsic. (rust-lang/stdarch#1285)
- Remove use of `#[rustc_deprecated]`
- Remove feature gates for stabilized features
- Change remaining _undefined_ functions to zero-init
- Use SPDX license format and update packed_simd crate link (rust-lang/stdarch#1297)
- Fix broken links (rust-lang/stdarch#1294)
- Import the asm macro in std_detect (rust-lang/stdarch#1290)
fix: wrong trait import suggestion for T:
The suggestion to bound `T` had an extra `:`.
```rust
fn foo<T:>(t: T) {
t.clone();
}
```
```
error[E0599]: no method named `clone` found for type parameter `T` in the current scope
--> src/lib.rs:2:7
|
2 | t.clone();
| ^^^^^ method not found in `T`
|
= help: items from traits can only be used if the type parameter is bounded by the trait
help: the following trait defines an item `clone`, perhaps you need to restrict type parameter `T` with it:
|
1 | fn foo<T: Clone:>(t: T) {
| ~~~~~~~~
```
Fixes: #95898
Document that DirEntry holds the directory open
I had a bug where holding onto DirEntry structs caused file descriptor exhaustion, and thought it would be good to document this.
Improve Rustdoc UI for scraped examples with multiline arguments, fix overflow in line numbers
This PR improves a few aspects of the scrape examples feature in Rustdoc.
* Only function names and not the full call expression are highlighted.
* For call-sites with multiline arguments, the minimized code viewer will scroll to the top of the call-site rather than the middle if the argument is larger than the viewer size, ensuring that the function name is visible.
* This fixes an issue where the line numbers column had a visible x-scroll bar.

Use mir constant in thir instead of ty::Const
This is blocked on https://github.com/rust-lang/rust/pull/94059 (does include its changes, the first two commits in this PR correspond to those changes) and https://github.com/rust-lang/rust/pull/93800 being reinstated (which had to be reverted). Mainly opening since `@lcnr` offered to give some feedback and maybe also for a perf-run (if necessary).
This currently contains a lot of duplication since some of the logic of `ty::Const` had to be copied to `mir::ConstantKind`, but with the introduction of valtrees a lot of that functionality will disappear from `ty::Const`.
Only the last commit contains changes that need to be reviewed here. Did leave some `FIXME` comments regarding future implementation decisions and some things that might be incorrectly implemented.

Fix broken link in coverage tools docs
During stabilization the link to example screenshot wad not updated, making rendered docs somewhat less useful. Move that screenshot from unstable book into rustc docs and make documentation point to that new place. Also remove `/img` in unstable book since there are no more any files there.
Always use system `python3` on MacOS
This PR includes 2 changes:
1. Always use the system Python found at `/usr/bin/python3` on MacOS
2. Removes the hard requirement on having `python` in your system path if you didn't specify alternatives. The proposed change will instead attempt to find and use in order: `python` -> `python3` -> `python2`. This change isn't strictly necessary but without any change to this check, the original issue inspiring this change will still exist.

Autolabel library PRs with T-libs
Continuation of https://github.com/rust-lang/highfive/pull/389
We're trying to improve the libs team review structure and part of that is defaulting PRs to the T-libs team to act as a mini-triage team for all the libs teams / project groups. Highfive doesn't do issue tagging so we will rely on triagebot to pre-triage for t-libs to post-triage :)
prevent opaque types from appearing in impl headers
cc `@lqd`
opaque types are not distinguishable from their hidden type at the codegen stage. So we could either end up with cases where the hidden type doesn't implement the trait (which will thus ICE) or where the hidden type does implement the trait (so we'd be using its impl instead of the one written for the opaque type). This can even lead to unsound behaviour without unsafe code.
Fixes https://github.com/rust-lang/rust/issues/86411.

rebase of #87382 plus some diagnostic tweaks
Fix suggestions in case of `T:` bounds
This PR fixes a corner case in `suggest_constraining_type_params` that was causing incorrect suggestions.
For the following functions:
```rust
fn a<T:>(t: T) { [t, t]; }
fn b<T>(t: T) where T: { [t, t]; }
```
We previously suggested the following:
```text
...
help: consider restricting type parameter `T`
|
1 | fn a<T: Copy:>(t: T) { [t, t]; }
| ++++++
...
help: consider further restricting this bound
|
2 | fn b<T>(t: T) where T: + Copy { [t, t]; }
| ++++++
```
Note that neither `T: Copy:` not `where T: + Copy` is a correct bound.
With this commit the suggestions are correct:
```text
...
help: consider restricting type parameter `T`
|
1 | fn a<T: Copy>(t: T) { [t, t]; }
| ++++
...
help: consider further restricting this bound
|
2 | fn b<T>(t: T) where T: Copy { [t, t]; }
| ++++
```

I've tried fixing #95898 here too, but got too confused with how `suggest_traits_to_import` works and what it does 😅
