Rollup merge of #51791 - GuillaumeGomez:minify-css, r=estebank 
Minify css

Sizes changes:

```
dark.css: 8821 => 7804 (~11%)
light.css: 8587 => 7565 (~11%)
rustdoc.css: 22364 => 17818 (~20%)
settings.css: 1384 => 1236 (~10%)
```

So obviously, the bigger the file, the bigger minification.

Rollup merge of #51786 - cuviper:stat64-pointers, r=Mark-Simulacrum 
Remove unnecessary stat64 pointer casts

In effect, these just casted `&mut stat64` to `*mut stat64`, twice.
That's harmless, but it masked a problem when this was copied to new
code calling `fstatat`, which takes a pointer to `struct stat`.  That
will be fixed by #51785, but let's remove the unnecessary casts here
too.

Link panic and compile_error docs

This adds documentation links between `panic!()` and `compile_error!()` as per #47275, which points out that they’re similar. It also adds a sentence to the `compile_error()` docs I thought could be added.

Rollup merge of #51104 - zackmdavis:dynamo, r=nikomatsakis 
add `dyn ` to display of dynamic (trait) types

~~I'm not sure we want the `dyn` in the E0277 "trait bound [...] is not satisfied" messages ("bound" sounds like a different thing in contrast to the names of specific trait-object types like `Box<dyn Trait>`), but I'm finding the code I would need to change that hard to follow—the [display object seems to](f0805a4421/src/librustc/traits/error_reporting.rs (L600)) be a [`Predicate::Trait`](f0805a4421/src/librustc/ty/mod.rs (L962)) variant, whose [`Display` implementation](f0805a4421/src/librustc/util/ppaux.rs (L1309)) calls `.print` on its `PolyTraitPredicate` member, [which is a type alias](f0805a4421/src/librustc/ty/mod.rs (L1112)) for `ty::Binder<TraitPredicate<'tcx>>`, whose [`Display` implementation](f0805a4421/src/librustc/util/ppaux.rs (L975-L985)) ... _&c._— so maybe it's time to pull-request this and see what reviewers think.~~

 Resolves #49277 (?).

Obligation forest cleanup

While looking at this code I was scratching my head about whether a node could appear in both `parent` and `dependents`. Turns out it can, but it's not useful to do so, so this PR cleans things up so it's no longer possible.

7d2fa4a4d2 Auto merge of #50630 - sharkdp:fix-50619, r=sfackler 
Fix possibly endless loop in ReadDir iterator

Certain directories in `/proc` can cause the `ReadDir` iterator to loop indefinitely. We get an error code (22) when calling libc's `readdir_r` on these directories, but `entry_ptr` is `NULL` at the same time, signalling the end of the directory stream.

This change introduces an internal state to the iterator such that the `Some(Err(..))` value will only be returned once when calling `next`. Subsequent calls will return `None`.

fixes #50619

fdd9cdc879 Auto merge of #50966 - leodasvacas:self-in-where-clauses-is-not-object-safe, r=nikomatsakis 
`Self` in where clauses may not be object safe

Needs crater, virtually certain to cause regressions.

In #50781 it was discovered that our object safety rules are not sound because we allow `Self` in where clauses without restrain. This PR is a direct fix to the rules so that we disallow methods with unsound where clauses.

This currently uses hard error to measure impact, but we will want to downgrade it to a future compat error.

Part of #50781.
