when checking pointee metadata, canonicalize the `Sized` check
Use `infcx.predicate_must_hold_modulo_regions` with a `Sized` obligation instead of just calling `ty.is_sized`, because the latter does not canonicalize region and type vars (and in the test case I added in this PR, there's a region var in the `ParamEnv`).

The docs for `Iterator::unzip` explain that it is kind of an inverse operation to `Iterator::zip` and guide the reader to the `zip` docs, but the `zip` docs don't let the user know that they can undo the `zip` operation with `unzip`. This change modifies the docs to help the user find `unzip`.
Remove `<mbe::TokenTree as Clone>`
`mbe::TokenTree` doesn't really need to implement `Clone`, and getting rid of that impl leads to some speed-ups.

errors: lazily load fallback fluent bundle
Addresses (hopefully) https://github.com/rust-lang/rust/pull/95667#issuecomment-1094794087.
Loading the fallback bundle in compilation sessions that won't go on to emit any errors unnecessarily degrades compile time performance, so lazily create the Fluent bundle when it is first required.

Optimization have improved over time and now LLVM manages to optimize more
in-place-collect noop-iterators to O(1) functions. This updates the codegen test to match.

fix: wrong trait import suggestion for T:
The suggestion to bound `T` had an extra `:`.
```rust
fn foo<T:>(t: T) {
t.clone();
}
```
```
error[E0599]: no method named `clone` found for type parameter `T` in the current scope
--> src/lib.rs:2:7
|
2 | t.clone();
| ^^^^^ method not found in `T`
|
= help: items from traits can only be used if the type parameter is bounded by the trait
help: the following trait defines an item `clone`, perhaps you need to restrict type parameter `T` with it:
|
1 | fn foo<T: Clone:>(t: T) {
| ~~~~~~~~
```

Document that DirEntry holds the directory open
I had a bug where holding onto DirEntry structs caused file descriptor exhaustion, and thought it would be good to document this.
Improve Rustdoc UI for scraped examples with multiline arguments, fix overflow in line numbers
This PR improves a few aspects of the scrape examples feature in Rustdoc.
* Only function names and not the full call expression are highlighted.
* For call-sites with multiline arguments, the minimized code viewer will scroll to the top of the call-site rather than the middle if the argument is larger than the viewer size, ensuring that the function name is visible.
* This fixes an issue where the line numbers column had a visible x-scroll bar.
