Using `F_KINFO` fcntl flag, the kf_structsize field needs to be set beforehand for that effect.
Remove reachable coverage without counters to maintain invariant that
either there is no coverage at all or there is a live coverage counter
left that provides the function source hash.
The motivating example would be a following closure:
```rust
let f = |x: bool| {
debug_assert!(x);
};
```
Which, with span changes from rust-lang#93967, with disabled debug assertions,
after the final CFG simplifications but before removal of dead blocks,
gives rise to MIR:
```rust
fn main::{closure#0}(_1: &[closure@a.rs:2:13: 2:22], _2: bool) -> () {
debug x => _2;
let mut _0: ();
bb0: {
Coverage::Expression(4294967295) = 1 - 2;
return;
}
...
}
```
Constify a few `(Partial)Ord` impls Only a few `impl`s are constified for now, as rust-lang#92257 has not landed in the bootstrap compiler yet and quite a few impls would need that fix. This unblocks rust-lang#92228, which unblocks marking iterator methods as `default_method_body_is_const`.
…imulacrum Implement `fs::get_path` for FreeBSD. Using `F_KINFO` fcntl flag, the kf_structsize field needs to be set beforehand for that effect.
correct the output of a `capacity` method example The output of this example in std::alloc is different from which shown in the comment. I have tested it on both Linux and Windows.
clarify how write_bytes can lead to UB due to invalid values Fixes rust-lang/unsafe-code-guidelines#330 Cc `@5225225`
…li-obk don't ICE on invalid dyn calls Due to rust-lang#50781 this is actually reachable. Fixes rust-lang/miri#2432 r? `@oli-obk`

```
Which also makes the initial instrumentation quite suspect, although
this pull request doesn't attempt to address that aspect directly.
Fixes rust-lang#98833.
