Don't run a publically reachable server in tests
This causes Windows Defender's firewall to pop up during tests to ask if I want to allow the test program to access the public Internet, since it was listening on `0.0.0.0` (the test passes regardless of how you respond to the modal, since the firewall only affects traffic outside of the computer, none of which actually happens in the test). The test server doesn't actually need to be publicly reachable, so this makes it so it is only reachable locally, which makes Windows Defender happy.
This prevents mistakes where the feature is in the list of incomplete
features but not actually a feature by making the incompleteness a part
of the declaration.
This creates a CSV with name "closure_profile_XXXXX.csv", where the
variable part is the process id of the compiler.
To profile a cargo project you can run one of the following depending on
if you're compiling a library or a binary:
```
cargo +stage1 rustc --lib -- -Zprofile-closures
cargo +stage1 rustc --bin -- -Zprofile-closures
```

Don't dist miri or rust-analyzer on stable or beta.
This prevents miri and rust-analyzer from being built for "dist" or "install" on the stable/beta channels. It is a nightly-only tool and should not be included.
Closes#86286
Fix type checking of return expressions outside of function bodies
This pull request fixes#86188. The problem is that the current code for type-checking `return` expressions stops if the `return` occurs outside of a function body, while the correct behavior is to continue type-checking the return value expression (otherwise an ICE happens later on because variables declared in the return value expression don't have a type).
Also, I have noticed that it is sometimes not obvious why a `return` is outside of a function body; for instance, in the example from #86188 (which currently causes an ICE):
```rust
fn main() {
[(); return || {
let tx;
}]
}
```
I have changed the error message to also explain why the `return` is considered outside of the function body:
```
error[E0572]: return statement outside of function body
--> ice0.rs:2:10
|
1 | / fn main() {
2 | | [(); return || {
| |__________^
3 | || let tx;
4 | || }]
| ||_____^ the return is part of this body...
5 | | }
| |_- ...not the enclosing function body

Add suspicious group
changelog: Introduce `clippy::suspicious` 🤔 group and move several lints into the group
Closes#6366. CC #6626.
A number of lints are moved from each of `correctness`, `style` and `complexity` groups. Notably I didn't move `suspicious_splitn` since I think that is a `correctness` lint despite the name.
Lints moved to `clippy::suspicious`:
* `blanket_clippy_restriction_lints` (was `clippy::style`)
* `empty_loop` (was `clippy::style`)
* `eval_order_dependence` (was `clippy::complexity`)
* `float_equality_without_abs` (was `clippy::correctness`)
* `for_loops_over_fallibles` (was `clippy::correctness`)
* `misrefactored_assign_op` (was `clippy::complexity`)
* `mut_range_bound` (was `clippy::complexity`)
* `mutable_key_type` (was `clippy::correctness`)
* `suspicious_arithmetic_impl` (was `clippy::correctness`)
* `suspicious_assignment_formatting` (was `clippy::style`)
* `suspicious_else_formatting` (was `clippy::style`)
* `suspicious_map` (was `clippy::complexity`)
* `suspicious_op_assign_impl` (was `clippy::correctness`)
* `suspicious_unary_op_formatting` (was `clippy::style`)
Fix typo in libs tracking issue template
Currently, the libs tracking issue template expands FCP as "final commenting period". Everywhere else, including in [the official explanation](https://rust-lang.github.io/rfcs/), it's expanded as "final comment period". That version also sounds a bit better. Accordingly, this PR changes the tracking issue template to use that version.

Reserve prefixed identifiers and literals (RFC 3101)
This PR denies any identifiers immediately followed by one of three tokens `"`, `'` or `#`, which is stricter than the requirements of RFC 3101 but may be necessary according to the discussion at [Zulip].
[Zulip]: https://rust-lang.zulipchat.com/#narrow/stream/268952-edition-2021/topic/reserved.20prefixes/near/238470099
The tracking issue #84599 says we'll add a feature gate named `reserved_prefixes`, but I don't think I can do this because it is impossible for the lexer to know whether a feature is enabled or not. I guess determining the behavior by the edition information should be enough.
Fixes#84599
2229: Capture box completely in move closures
Even if the content from box is used in a sharef-ref context,
we capture the box entirerly.
This is motivated by:
1) We only capture data that is on the stack.
2) Capturing data from within the box might end up moving more data than
the user anticipated.
