Document rustdoc with `--document-private-items`

The `tool_doc` macro introduced in #86737 did not use `false` as the default value for `binary` when it is not provided, so the `if` is not even expanded and thus the argument is never provided if the `binary` argument isn't.

Resolves #86900

Rollup merge of #86956 - cuviper:unalias-every, r=m-ou-se
Revert "Add "every" as a doc alias for "all"."

This reverts commit 35450365ac (#81697) for "every" and closes #86554 in kind for "some".

The new [doc alias policy](https://std-dev-guide.rust-lang.org/documentation/doc-alias-policy.html) is that we don't want language-specific aliases like these JavaScript names, and we especially don't want to conflict with real names. While "every" is okay in the latter regard, its natural pair "some" makes a doc-search collision with `Option::Some`.

Fix ICE when misplaced visibility cannot be properly parsed

Fixes #86895

The issue was that a failure to parse the visibility was causing the original error to be dropped before being emitted.

The resulting error isn't quite as nice as when the visibility is parsed properly, but I'm not sure which error to prioritize here. Displaying both errors might be too confusing.

Sync rustc_codegen_cranelift

The main hightlight this sync is basic support for AArch64. Most things should work on Linux, but there does seem to be an ABI incompatibility causing proc-macros to crash, see https://github.com/bjorn3/rustc_codegen_cranelift/issues/1184. Thanks to ```@afonso360``` for implementing all Cranelift features that were necessary to compile for AArch64 using cg_clif. Also thanks to ```@shamatar``` for implementing the `llvm.x86.addcarry.64` and `llvm.x86.subborrow.64` llvm intrinsics used by num-bigint (https://github.com/bjorn3/rustc_codegen_cranelift/pull/1178) and ```@eggyal``` for implementing multi-threading support for the lazy jit mode.

Rollup merge of #86812 - FabianWolff:recover-dyn-mut, r=petrochenkov
Recover from `&dyn mut ...` parse errors

Consider this example:
```rust
fn main() {
    let r: &dyn mut Trait;
}
```
This currently leads to:
```
error: expected one of `!`, `(`, `;`, `=`, `?`, `for`, lifetime, or path, found keyword `mut`
 --> src/main.rs:2:17
  |
2 |     let r: &dyn mut Trait;
  |                 ^^^ expected one of 8 possible tokens

error: aborting due to previous error
```
However, especially for beginners, I think it is easy to get `&dyn mut` and `&mut dyn` confused. With my changes, I get a help message, and the parser even recovers:
```
error: `mut` must precede `dyn`
 --> test.rs:2:12
  |
2 |     let r: &dyn mut Trait;
  |            ^^^^^^^^ help: place `mut` before `dyn`: `&mut dyn`

error[E0405]: cannot find trait `Trait` in this scope
 --> test.rs:2:21
  |
2 |     let r: &dyn mut Trait;
  |                     ^^^^^ not found in this scope

Support lint tool names in rustc command line options

When rustc is running without a lint tool such as clippy enabled, options for lints such as `clippy::foo` are meant to be ignored. This was already working for those specified by attrs, such as `#![allow(clippy::foo)]`, but this did not work for command line arguments like `-A clippy::foo`. This PR fixes that issue.

Note that we discovered this issue while discussing https://github.com/rust-lang/cargo/issues/5034.
