Rollup merge of #94754 - c410-f3r:nice-error, r=lcnr 
Warn users about `||` in let chain expressions

Or more specifically, warn that `||` operators are forbidden.

This PR is simple so I guess anyone can review 🤷

Rollup merge of #93057 - frengor:iter_collect_into, r=m-ou-se 
Add Iterator::collect_into

This PR adds `Iterator::collect_into` as proposed by ``@cormacrelf`` in #48597 (see https://github.com/rust-lang/rust/pull/48597#issuecomment-842083688).
Followup of #92982.

This adds the following method to the Iterator trait:

```rust
fn collect_into<E: Extend<Self::Item>>(self, collection: &mut E) -> &mut E
```

Rollup merge of #92541 - asquared31415:from-docs, r=m-ou-se 
Mention intent of `From` trait in its docs

This pr is a docs modification to add to the documentation of the `From` trait a note about its intent as a perfect conversion.  This is already stated in the `TryFrom` docs so this is simply adding that information in a more visible way.

Rollup merge of #91804 - woppopo:const_clone, r=oli-obk 
Make some `Clone` impls `const`

Tracking issue: #91805
`Clone::clone_from` and some impls (Option, Result) bounded on `~const Drop`.

```rust
// core::clone
impl const Clone for INTEGER
impl const Clone for FLOAT
impl const Clone for bool
impl const Clone for char
impl const Clone for !
impl<T: ?Sized> const Clone for *const T
impl<T: ?Sized> const Clone for *mut T
impl<T: ?Sized> const Clone for &T

// core::option
impl<T> const Clone for Option<T>
where
    T: ~const Clone + ~const Drop

// core::result
impl<T, E> const Clone for Result<T, E>
where
    T: ~const Clone + ~const Drop,
    E: ~const Clone + ~const Drop,

// core::convert
impl const Clone for Infallible

// core::ptr
impl<T: ?Sized> const Clone for NonNull<T>
impl<T: ?Sized> const Clone for Unique<T>
```

7f4f4fc34c Use indexing instead of .get_unchecked() for LUT lookup 
Based on @paolobarbolini's tip that the unsafe block was unnecessary in
this case.

Not much left of `hexify()` after this, so seemed clearer to just inline
it.

32d7f8145a diagnostics: use rustc_on_unimplemented to recommend [].iter() 
To make this work, the `#[rustc_on_unimplemented]` data needs to be used to
report method resolution errors, which is most of what this commit does.

Fixes #94581

unix: reduce the size of DirEntry

On platforms where we call `readdir` instead of `readdir_r`, we store
the name as an allocated `CString` for variable length. There's no point
carrying around a full `dirent64` with its fixed-length `d_name` too.
