fb05be00df Match scalar-pair-bool more flexibly for LLVM 11 
LLVM 11 started using `phi` and `select` for `fn pair_i32_bool`, which
is still valid, but harder to match than the simple instructions we were
getting before. We'll just check that the unpacked args are directly
referenced in any way, and call it good.

df4bafc360 Don't make clang use gcc's include-fixed 
This was breaking `#include_next <limits.h>`, such that we weren't
getting definitions of `PATH_MAX` and `_POSIX_ARG_MAX`.

663d2f5cd3 Auto merge of #75171 - amosonn:new_zeroed_slice, r=Amanieu 
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).

e2326a1eec Treat a NULL return from dlsym as an error on illumos 
This works around behavior observed on illumos in #74469, in which
foreign code (libc according to the OP) was racing with rustc to check
`dlerror`.

766fcb0b01 Refactor dynamic library error checking on *nix 
The old code was checking `dlerror` more often than necessary, since the
return value of `dlopen` indicates whether an error occurred.

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.

9db0b86f4e rustdoc: Cache traits implemented by a type 
This avoids taking the slow path several thousand times in a row.

- Fallback to all traits if the traits in scope are unknown
- Use a rustdoc thread_local cache instead of a query

The set of traits implemented by a type is not stable across crates:
there could be new traits added in a new crate.

- Use DocContext instead of a thread-local

42232ba70a rustdoc: Add support for associated items even outside the impl itself 
Previously, associated items would only be available for linking
directly on the `impl Trait for Type`. Now they can be used anywhere.

- Make `item` for resolve mandatory
- Refactor resolving associated items into a separate function
- Remove broken trait_item logic
- Don't skip the type namespace for associated items
- Only call `variant_field` for `TypeNS`
- Add test for associated items
- Use exhaustive matches instead of wildcards

Wildcards caused several bugs while implementing this.

a97d65d6e4 rustdoc: Rename misleading function 
- `is_associated` -> `is_type_alias`

`is_associated` is not a good name for what this is doing. If you look at
https://github.com/rust-lang/rust/pull/74489/files#diff-6a301d597807ee441a41e7237800563dR296,
is_associated() and as_assoc_kind() do completely different things, but
from the name it sounds like they're similar.
