Rollup merge of #100371 - xfix:inline-from-bytes-with-nul-unchecked-rt-impl, r=scottmcm

Inline CStr::from_bytes_with_nul_unchecked::rt_impl

Currently `CStr::from_bytes_with_nul_unchecked::rt_impl` is not being inlined. The following function:

```rust
pub unsafe fn from_bytes_with_nul_unchecked(bytes: &[u8]) {
    CStr::from_bytes_with_nul_unchecked(bytes);
}
```

Outputs the following assembly on current nightly

```asm

Meanwhile on beta this provides the following assembly:

```asm

This pull request adds `#[inline]` annotation to`rt_impl` to fix a code generation regression for `CStr::from_bytes_with_nul_unchecked`.

The idea here is that generally, rustc is split into things which can assume its inputs are well formed[^1], and things which have verify that themselves.

Generally most predicates should only deal with well formed inputs, e.g. a `&'a &'b (): Trait` predicate should be able to assume that `'b: 'a` holds. Normalization can loosen wf requirements (see #91068) and must therefore not be used in places which still have to check well formedness. The only such place should hopefully be `WellFormed` predicates

Don't ICE while suggesting updating item path.

When an item isn't found, we may suggest an appropriate import to `use`. Along with that, we also suggest updating the path to work with the `use`. Unfortunately, if the code in question originates from a macro, the span used to indicate which part of the path needs updating may not be suitable and cause an ICE (*). Since, such code is not adjustable directly by the user without modifying the macro, just skip the suggestion in such cases.

(*) The ICE happens because the emitter want to indicate to the user what code to delete by referencing a certain span. But in this case, said span has `lo == hi == 0` which means it thinks it's a dummy span. Adding a space before the proc macro attribute is enough to stop it from ICE'ing but even then the suggestion doesn't really make any sense:
```
help: if you import `DataStore`, refer to it directly
  |
1 -  #[dbstruct::dbstruct]
1 +  #[dbstruct::dbstruct]
```

Since suggestions are best-effort, I just gated this one on `can_be_used_for_suggestions` which catches cases like this.

Implement `#[rustc_default_body_unstable]`

This PR implements a new stability attribute — `#[rustc_default_body_unstable]`.

`#[rustc_default_body_unstable]` controls the stability of default bodies in traits.
For example:
```rust
pub trait Trait {
    #[rustc_default_body_unstable(feature = "feat", isssue = "none")]
    fn item() {}
}
```
In order to implement `Trait` user needs to either
- implement `item` (even though it has a default implementation)
- enable `#![feature(feat)]`

This is useful in conjunction with [`#[rustc_must_implement_one_of]`](https://github.com/rust-lang/rust/pull/92164), we may want to relax requirements for a trait, for example allowing implementing either of `PartialEq::{eq, ne}`, but do so in a safe way — making implementation of only `PartialEq::ne` unstable.

Implement special-cased projection error message for some common traits

Not sure what the best phrasing is, but I feel like these are more clear than the plain `<Type as Iterator>::Output == Type` messages.

If this is actually a good idea, are there any other traits this could benefit?

I haven't understood the difference between these before, but
`@compiler-errors` helped me clear it up. Hopefully this will help other
people who've been confused!
