Remove ExplicitSelf from HIR
`self` argument is already kept in the argument list and can be retrieved from there if necessary, so there's no need for the duplication.
The same changes can be applied to AST, I'll make them in the next breaking batch.
The first commit also improves parsing of method declarations and fixes https://github.com/rust-lang/rust/issues/33413.

Especially in cases like the one in the test file, this can blow
up the docs big time if string constants in the code contain HTML.
But also other constants can contain special chars (e.g. `&` as an
operator in constant expressions).
rustdoc: Cleanup ABI rendering
Use a common method for rendering `extern "<abi>"`.
This now consistently shows `extern fn` rather than `extern "C" fn`.
rustdoc: refine cross-crate impl inlining
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.

.. and also applies the reachability checking to cross-crate links.

Automated conversion using the untry tool [1] and the following command:
```
$ find -name '*.rs' -type f | xargs untry
```
at the root of the Rust repo.

paths, and construct paths for all definitions. Also, stop rewriting
DefIds for closures, and instead just load the closure data from
the original def-id, which may be in another crate.
Some cases displayed negative impls as positive, and some were missing
where clauses. This factors all the impl formatting into one
function so the different cases can't get out of sync again.
rustdoc: Associated type fixes
The first commit fixes a bug with "dud" items in the search index from
misrepresented `type` items in trait impl blocks.
For a trait *implementation* there are typedefs which are the types for
that particular trait and implementor. Skip these in the search index.
There were lots of dud items in the search index due to this (search for
Item, Iterator's associated type).
Add a boolean to clean::TypedefItem so that it tracks whether the it is
a type alias on its own, or if it's a `type` item in a trait impl.
The second commit fixes a bug that made signatures and where bounds
using associated types (if they were not on `Self`) incorrect.
The third commit fixes so that where clauses in type alias definititons
are shown.
Fixes#22442Fixes#24417Fixes#25769
Functions such as `fn foo<I: Iterator>(x: I::Item)` would not
render correctly and displayed `I` instead of `I::Item`. Same thing
with `I::Item` appearing in where bounds.
This fixes the bug by using paths for generics.
Fixes#24417
- add feature gate
- add basic tests
- adjust parser to eliminate conflict between `const fn` and associated
constants
- allow `const fn` in traits/trait-impls, but forbid later in type check
- correct some merge conflicts
This commit is an overhaul to how rustdoc deals with stability of the standard
library. The handling has all been revisited with respect to Rust's current
approach to stability in terms of implementation as well as the state of the
standard library today. The high level changes made were:
* Stable items now have no marker by default
* Color-based small stability markers have been removed
* Module listings now fade out unstable/deprecated items slightly
* Trait methods have a separate background color based on stability and also
list the reason that they are unstable.
* `impl` blocks with stability no longer render at all. This may be re-added
once the compiler recognizes stability on `impl` blocks.
* `impl` blocks no longer have stability of the methods implemente indicated
* The stability summary has been removed
Closes#15468Closes#21674Closes#24201
* All bounds are now discovered through the trait to be inlined.
* The `?Sized` bound now renders correctly for inlined associated types.
* All `QPath`s (`<A as B>::C`) instances are rendered as `A::C` where `C` is a
hyperlink to the trait `B`. This should improve at least how the docs look at
least.
* Supertrait bounds are now separated and display as the source lists them.
Closes#20727Closes#21145
All methods listed in "Trait Implementations" now hyperlink to the source trait
instead of themselves, allowing easy browsing of the documentation of a trait
method.
Closes#17476
