Set release channel on non-dist builders
Toolstate publication only runs if the channel is "nightly" and
previously the toolstate builders did not know that the channel was
nightly (since they are not dist builders).
A look through bootstrap seems to indicate that nothing should directly
depend on the channel being set to `-dev` on the test builders, though
this may cause some problems with UI tests (if for some reason they're
dumping the channel into stderr), but we cannot find evidence of such so
hopefully this is fine.

Add more delegations to the fmt docs and add doctests
HI,
this is a continuation to #67021
I replaced the `Debug` example with one that use the `Debug*` helpers so that padding etc will work too.
I also added asserts for the doctests as @RalfJung asked :)
The only thing I left with the `write!` macro is the `Display` example as I didn't know if there's a better way to do that.

After #62550, it is no longer possible for `slice`
to be other than `None | Some(Binding(..) | Wild)`.
In particular, `lower_pat_slice` may never generate
`Some(Array(..) | Slice(..))` and so there is nothing
to flatten into `slice`.
The code is dead because `check_pat_slice` will never have
`expected = ty::Ref(...)` due to default-binding-modes
(see `is_non_ref_pat`, `peel_off_references`).
Moreover, if the type is not `ty::Array(_) | ty::Slice(_)`
then `check_pat_slice` enters an error branch.

Suggest associated type when the specified one cannot be found
Fixes#67386, so code like this:
```
use std::ops::Deref;
fn homura<T: Deref<Trget = i32>>(_: T) {}
fn main() {}
```
results in:
```
error[E0220]: associated type `Trget` not found for `std::ops::Deref`
--> type-binding.rs:6:20
|
6 | fn homura<T: Deref<Trget = i32>>(_: T) {}
| ^^^^^^^^^^^ help: there is an associated type with a similar name: `Target`
error: aborting due to previous error
```
(The `help` is new)
I used an `all_candidates: impl Fn() -> Iterator<...>` instead of `collect`ing to avoid the cost of allocating the Vec when no errors are found, at the expense of a little added complexity.

std: Implement `LineWriter::write_vectored`
This commit implements the `write_vectored` method of the `LineWriter`
type. First discovered in bytecodealliance/wasmtime#629 the
`write_vectored` method of `Stdout` bottoms out here but only ends up
writing the first buffer due to the default implementation of
`write_vectored`.
Like `BufWriter`, however, `LineWriter` can have a non-default
implementation of `write_vectored` which tries to preserve the
vectored-ness as much as possible. Namely we can have a vectored write
for everything before the newline and everything after the newline if
all the stars align well.
Also like `BufWriter`, though, special care is taken to ensure that
whenever bytes are written we're sure to signal success since that
represents a "commit" of writing bytes.

Switch bootstrap to 1.41
This updates the version number for master to 1.42 and switches the bootstrap compiler to yesterday's beta. Fallout of cfg(bootstrap) changes is also dealt with.
`hir::BorrowKind::Raw` borrows and casting a reference to a raw
pointer no longer do a reborrow followed by a cast. Instead we
dereference and take the address.
This operator creates a raw pointer to a Place directly, without first
creating a reference. See RFC #2582 for motivation.
The Rvalue is currently unused.
