This changes the current rule that impls within `doc(hidden)` modules
aren't inlined, to only inlining impls where the implemented
trait and type are reachable in documentation.
resolve: Improve duplicate glob detection
This fixes a bug introduced in #31726 in which we erroneously allow multiple imports of the same item under some circumstances.
More specifically, we erroneously allow a module that is in a cycle of glob re-exports to have other re-exports (besides the glob from the cycle).
For example,
```rust
pub fn f() {}
mod foo {
pub use f; // (1) This defines `foo::f`.
pub use bar::*; // (3) This also defines `foo::f`, which should be a duplicate error but is currently allowed.
}
mod bar {
pub use foo::*; // (2) This defines `bar::f`.
}
```
A module in a glob re-export cycle can still have `pub` items after this PR. For example,
```rust
mod foo {
pub fn f() {}; // (1) This defines `foo::f`.
pub use bar::*; // (3) This is not a duplicate error since items shadow glob-imported re-exports (cf #31337).
}
mod bar {
pub use foo::*; // (2) This defines `bar::f`.
}
```

rustbuild: Migrate tidy checks to Rust
This commit rewrites all of the tidy checks we have, namely:
* featureck
* errorck
* tidy
* binaries
into Rust under a new `tidy` tool inside of the `src/tools` directory. This at
the same time deletes all the corresponding Python tidy checks so we can be sure
to only have one source of truth for all the tidy checks.
cc #31590
This verifies that the crates listed in the `[dependencies]` section of
`Cargo.toml` are a subset of the crates listed in `lib.rs` for our in-tree
crates. This should help ensure that when we refactor crates over time we keep
these dependency lists in sync.
Describe more platform-specific behaviors of `std::fs::rename`
I did some tests myself regarding the situation when both `from` and `to` exist, and the results were:
On Linux:
`from` | `to` | Result
---- | ---- | ----
Directory | Directory | Ok
Directory | File | Error
File | Directory | Error
File | File | Ok
On Windows:
`from` | `to` | Result
---- | ---- | ----
Directory | Directory | Error
Directory | File | Ok
File | Directory | Error
File | File | Ok
This is a bit against the official MSDN documentation, which says "(`MOVEFILE_REPLACE_EXISTING`) cannot be used if `lpNewFileName` or `lpExistingFileName` names a directory." As evidenced above, `lpExistingFileName` *can* be a directory.
I also mentioned the atomicity of the operation.
Fixes#31301.

rustdoc: Fix testing no_run code blocks
This was a regression introduced by #31250 where the compiler deferred returning
the results of compilation a little too late (after the `Stop` check was looked
at). This commit alters the stop point to first try to return an erroneous
`result` and only if it was successful return the sentinel `Err(0)`.
Closes#31576

Match signed/unsigned integer type docs
* Copy documentation from signed implementation to unsigned implementation, where necessary.
A few functions had elaborate docs in the signed version but not in the unsigned version. This probably happenned because the signed version is at the top and the author didn't realize they had to update the documentation in both locations.
* Use signed integers in signed documentation, where possible.

Bit-magic for faster is_char_boundary

both sub-inequalities. This patch replaces it with bit magic.

Thanks for all your hard work!
This is in reference to #32733
I know there has been a discussion about this on PR #32538 so you are welcome to keep the code as is or merge my documentation in.
Let me know what you think and/or if you want me to modify anything!

Discovered this while hunting for 1.8 features. I'm afraid there may be more of these that are incorrect and we may have created a mess.
Blacklist fn item types from being used with variadic functions.
Fixes#32201 by adding fn types to the variadic blacklist which currently includes `bool`, `i8`, `u8`, `i16`, `u16` and `f32`.
