Fix small typo in time comment

I was reading through [this PR](https://github.com/rust-lang/rust/pull/77727/files) and noticed a [small typo](https://github.com/rust-lang/rust/pull/77727/files#diff-3183738c82f747fd92bb573712073aa384b16e14d154bf2df18f41077edc31cbR240) smuggled though. This just fixes that.

This doesn't need a `changelog-seen` version bump because the old values aren't accepted anymore, meaning anyone who was using this had to change it already.

b9c403be11 Auto merge of #79472 - Aaron1011:new-remove-pretty-print-hack, r=petrochenkov
Replace pretty-print/compare/retokenize hack with targeted workarounds

Based on https://github.com/rust-lang/rust/pull/78296
cc https://github.com/rust-lang/rust/issues/43081

The 'pretty-print/compare/retokenize' hack is used to try to avoid passing an outdated `TokenStream` to a proc-macro when the underlying AST is modified in some way (e.g. cfg-stripping before derives). Unfortunately, retokenizing throws away spans (including hygiene information), which causes issues of its own. Every improvement to the accuracy of the pretty-print/retokenize comparison has resulted in non-trivial ecosystem breakage due to hygiene changes. In extreme cases, users deliberately wrote unhygienic `macro_rules!` macros (likely because they did not realize that the compiler's behavior was a bug).

Additionaly, the comparison between the original and pretty-printed/retoknized token streams comes at a non-trivial runtime cost, as shown by https://github.com/rust-lang/rust/pull/79338

This PR removes the pretty-print/compare/retokenize logic from `nt_to_tokenstream`. We only discard the original `TokenStream` under two circumstances:
* Inner attributes are used (detected by examining the AST)
* `cfg`/`cfg_attr` processing modifies the AST. This is detected by making the visitor update a flag when it performs a modification, instead of trying to detect the modification after-the-fact. Note that a 'matching' `cfg` (e.g. `#[cfg(not(FALSE)]`) does not actually get removed from the AST, allowing us to preserve the original `TokenStream`.

In all other cases, we preserve the original `TokenStream`.

This could use a bit of refactoring/renaming - opening for a Crater run.

158f8d034b Auto merge of #80014 - jyn514:box-item-kind, r=nnethercote
[rustdoc] Box ItemKind to reduce the size of `Item`

This brings the size of `Item` from

```
[src/librustdoc/lib.rs:103] std::mem::size_of::<Item>() = 536
```

to

```
[src/librustdoc/lib.rs:103] std::mem::size_of::<Item>() = 136
```

This is an alternative to https://github.com/rust-lang/rust/pull/79967; I don't think it makes sense to make both changes.

Helps with #79103.

Rollup merge of #80431 - xfix:add-chr-as-doc-alias, r=steveklabnik
Add "chr" as doc alias to char::from_u32

Many programming languages provide a function called `chr` - Perl, Python, PHP, Visual Basic, SQL. This change makes `char::from_u32` easier to discover in the documentation.

`ord` is not added as its name conflicts with `Ord` trait, and it's not exactly clear what it could point to (`<u32 as From<char>>::from`?). I don't think it's exactly necessary, as `char::from_u32` documentation page says you can do reverse conversion with `as` operator anyway.

( :) ) from the names and what I know generally about type inference to
add some basic documentation.
