The primary purpose of this commit is to introduce the
dyn_star flag so we can begin experimenting with implementation.
In order to have something to do in the feature gate test, we also add
parser support for `dyn* Trait` objects. These are currently treated
just like `dyn Trait` objects, but this will change in the future.
Note that for now `dyn* Trait` is experimental syntax to enable
implementing some of the machinery needed for async fn in dyn traits
without fully supporting the feature.
rustdoc: remove no-op `#search`
The margin rule was added in c729e4dca7 to remove an unnecessary left margin that was present on desktop. This desktop-mode margin was itself removed in 135281ed15.
The padding rule was added in 135281ed15 when converting the rule for `#main`, but didn't do anything even then.
Update browser UI test 0 10
The biggest change from this browser-ui-test update is the upgrade of the puppeteer version to `17.1.3` (the latest in short).
I also added the command `click-with-offset` to still allow us to click on the `[-]` part.

Check that the types in return position `impl Trait` in traits are well-formed
This effectively duplicates `check_associated_type_bounds`, but that shouldn't be for long, since we're going to remove it once we refactor RPITITs into regular associated items.
Fixes#101663

We don't check
```rust
trait Foo {
fn bar() -> impl ?Sized;
}
```
currently, but that's for a different reason, which is that we don't currently check that a trait function's return type is sized (i.e. `fn bar() -> [u8]` also works in a trait).
Add inline-llvm option for disabling/enabling LLVM inlining
In this PR, a new -Z option `inline-llvm` is added in order to be able to turn on/off LLVM inlining.
The capability of turning on/off inlining in LLVM backend is needed for testing performance implications of using recently enabled inlining in rustc's frontend (with -Z inline-mir=yes option, #91743). It would be interesting to see the performance effect using rustc's frontend inlining only without LLVM inlining enabled. Currently LLVM is still doing inlining no mater what value inline-mir is set to. With the option `inline-llvm` being added in this PR, user can turn off LLVM inlining by using `-Z inline-llvm=no` option (the default of inline-llvm is 'yes', LLVM inlining enabled).
Fix ICE in opt_suggest_box_span
We were _totally_ mishandling substs and obligations in `opt_suggest_box_span`, so I reworked that function pretty heavily.
Also some drive-by changes, namely removing `ret_type_span`.
Fixes#101465

Only encode return-position `impl Trait` in trait when parent function has a default body
Semi-blocked on #101679, because I can't currently write a test for when we _should_ encode the type of the return-position `impl Trait` in trait, which is when a trait has a default function body, like so:
```rust
trait Foo {
fn bar() -> impl Sized { }
}
```
Though this can land even without #101679, since it does prevent ICEs from occuring any time you use `#![feature(return_position_impl_trait_in_trait)]` in a library, which is kind annoying.
Simplify codeblock and their associated tooltip
It is based on https://github.com/rust-lang/rust/pull/101600 so it needs to wait for this one to be merged first.
This PR does two things:
* Remove CSS class duplication by setting CSS classes such as `compile_fail` directly on the `div` wrapping both the codeblock and the tooltip.
* Simplify DOM: no need to wrap the tooltip into a `<div>`, it can work just as well without it.
You can test it [here](https://rustdoc.crud.net/imperio/codeblock-tooltip/std/string/struct.String.html#deref).

The `<*const T>::guaranteed_*` methods now return an option for the unknown case
cc https://github.com/rust-lang/rust/issues/53020#issuecomment-1236932443
I chose `0` for "not equal" and `1` for "equal" and left `2` for the unknown case so backends can just forward to raw pointer equality and it works ✨
