dc3304c341 Turn may_have_side_effect into an associated constant 
The `may_have_side_effect` is an implementation detail of `TrustedRandomAccess`
trait. It describes if obtaining an iterator element may have side effects. It
is currently implemented as an associated function.

Turn `may_have_side_effect` into an associated constant. This makes the
value immediately available to the optimizer.

c0e3a1b096 Add to_raw_parts methods to *const, *mut, and NonNull 
These are not named `into_` because they do not consume their receiver
since raw pointers are `Copy`.

937d580a25 Add ptr::from_raw_parts, ptr::from_raw_parts_mut, and NonNull::from_raw_parts 
The use of module-level functions instead of associated functions
on `<*const T>` or `<*mut T>` follows the precedent of
`ptr::slice_from_raw_parts` and `ptr::slice_from_raw_parts_mut`.

8e54a21139 Auto merge of #81238 - RalfJung:copy-intrinsics, r=m-ou-se 
directly expose copy and copy_nonoverlapping intrinsics

This effectively un-does https://github.com/rust-lang/rust/pull/57997. That should help with `ptr::read` codegen in debug builds (and any other of these low-level functions that bottoms out at `copy`/`copy_nonoverlapping`), where the wrapper function will not get inlined. See the discussion in https://github.com/rust-lang/rust/pull/80290 and https://github.com/rust-lang/rust/issues/81163.

Increment `self.index` before calling `Iterator::self.a.__iterator_ge…

…`t_unchecked` in `Zip` `TrustedRandomAccess` specialization

Otherwise if `Iterator::self.a.__iterator_get_unchecked` panics the
index would not have been incremented yet and another call to
`Iterator::next` would read from the same index again, which is not
allowed according to the API contract of `TrustedRandomAccess` for
`!Clone`.

66f4883308 [librustdoc] Reform lang string token splitting 
Only split doctest lang strings on `,`, ` `, and `\t`. Additionally, to
preserve backwards compatibility with pandoc-style langstrings, strip a
surrounding `{}`, and remove leading `.`s from each token.

Prior to this change, doctest lang strings were split on all
non-alphanumeric characters except `-` or `_`, which limited future
extensions to doctest lang string tokens, for example using `=` for
key-value tokens.

This is a breaking change, although it is not expected to be disruptive,
because lang strings using separators other than `,` and ` ` are not
very common

52bc54efff Rollup merge of #81697 - xfix:every-doc-alias, r=Mark-Simulacrum 
Add "every" as a doc alias for "all".

This matches [Array#every](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/every) in JavaScript.

Oddly enough, `core::iter::Iterator::all` appears twice. This appears to be a rustdoc bug which I decided to fill in as #81696.
