New zeroed slice
Add to #63291 the methods
```rust
impl<T> Box<[T]> { pub fn new_zeroed_slice(len: usize) -> Box<[MaybeUninit<T>]> {…} }
impl<T> Rc<[T]> { pub fn new_zeroed_slice(len: usize) -> Rc<[MaybeUninit<T>]> {…} }
impl<T> Arc<[T]> { pub fn new_zeroed_slice(len: usize) -> Arc<[MaybeUninit<T>]> {…} }
```
as suggested in https://github.com/rust-lang/rust/issues/63291#issuecomment-605511675 .
Also optimize `{Rc, Arc}::new_zeroed` to use `alloc_zeroed`, otherwise they are no more efficient than using `new_uninit` and zeroing the memory manually (which was the original implementation).
Move to intra-doc links for library/core/src/alloc/{layout, global, mod}.rs
Helps with #75080. The files already contained intra-doc links, so there are only minor changes.
@rustbot modify labels: T-doc, A-intra-doc-links, T-rustdoc
Known issues:
* [`handle_alloc_error`]: Link from `core` to `alloc` could not be resolved.
* [`slice`]: slice is a primitive type, but could not be resolved; had to use [`crate::slice`] instead.
cargotest: fix clippy warnings
Fixes clippy::redundant_static_lifetimes and clippy::toplevel_ref_arg
I also replaced some .expect("") calls with .unwrap()s since there was no message passed by the .expect() anyway.
Missing doc examples lint improvements
Fixes#75719.
To be merged after #75718 (only the two last commits are from this PR).
Since you already reviewed #75718, I'll set you as reviewer here as well. :)

Don't count variants/fields/consts/associated types in doc-coverage doc examples
Fixes#75714.
I think I'll need to update the equivalent lint too. Creating an issue for that!

Split `astconv.rs` into its own submodule
Fixes#67418
This changed induced a few changes across the Type checker, but only there. Mostly, it was just renaming `Self::` into something else to call specific methods from a subtrait instead of having a 2500+ lines one.
I split up the `astconv.rs` file into its own module. This way, directives such as
```rust
use crate::astconv::AstConv;
```
are still valid, and doing
```rust
use crate::astconv::{AstConv, AstConvGeneric};
```
is possible
(instead of having two modules, one named `astconv_generic.rs` for example and `astconv.rs`)
I'm not entirely sure that the name `AstConvGeneric` is a good one. However, only methods related to lifetimes or generics have been moved over to this module. Sorry about the large diff.
I'd be very happy to make any correction you deem necessary.

Move to intra-doc links for /library/core/src/intrinsics.rs
Helps with #75080.

Known issues:
* The following f32 and f64 primitive methods cannot be resolved:
f32/f64::powi
f32/f64::sqrt
f32/f64::sin
f32/f64::cos
f32/f64::powf
f32/f64::exp
f32/f64::exp2
f32/f64::ln
f32/f64::log2
f32/f64::log10
f32/f64::mul_add
f32/f64::abs
f32/f64::copysign
f32/f64::floor
f32/f64::ceil
f32/f64::trunc
f32/f64::round
* Links from core to std:
[`std::pointer::*`]
[`std::process::abort`]
[`from_raw_parts`]
[`Vec::append`]
* Links with anchors?
I provided a separate commit that replaced links with anchors by intra-doc links.
Here the anchor location information gets lost, so its questionable whether to
actually replace those links.

enable align_to tests in Miri
With https://github.com/rust-lang/miri/issues/1074 resolved, we can enable these tests in Miri.
I also tweaked the test sized to get reasonable execution times with decent test coverage.
