Only use Fira Sans for the first `td` in item lists
Fixes#77516.
Fixes an issue where links in the one-line version of an item's docs
would be in Fira Sans, while the rest would be in a serifed font.
Change DocFragments from enum variant fields to structs with a nested enum
This makes the code a lot easier to work with. It also makes it easier
to add new fields without updating each variant and `match`
individually.
- Name the `Kind` variant after `DocFragmentKind` from `collapse_docs`
- Remove unneeded impls
Progress towards https://github.com/rust-lang/rust/issues/77254.

Improve rustdoc error for failed intra-doc link resolution
The previous error was confusing since it made it sound like you can't
link to items that are defined outside the current module.
Also suggested importing the item.

Resolve `crate` in intra-doc links properly across crates
Closes https://github.com/rust-lang/rust/issues/77193; see https://github.com/rust-lang/rust/issues/77193#issuecomment-699065946 for an explanation of what's going on here.
~~This also fixes the BTreeMap docs that have been broken for a while; see the description on the second commit for why and how.~~ Nope, see the second commit for why the link had to be changed.

`@dylni` note that this doesn't solve your original problem - now _both_ `with_code` and `crate::with_code` will be broken links. However this will fix a lot of other broken links (in particular I think https://docs.rs/sqlx/0.4.0-beta.1/sqlx/query/struct.Query.html is because of this bug). I'll open another issue for resolving additional docs in the new scope.
Add option to pass a custom codegen backend from a driver
This allows the driver to pass information to the codegen backend. For example the headcrab debugger may in the future want to use cg_clif to JIT code to be injected in the debuggee. This would PR make it possible to tell cg_clif which symbol can be found at which address and to tell it to inject the JITed code into the right process.
This PR may also help with https://github.com/rust-lang/miri/pull/1540 by allowing miri to provide a codegen backend that only emits metadata and doesn't perform any codegen.

This is not ideal because it means `deny(broken_intra_doc_links)` will
no longer `deny(private_intra_doc_links)`. However, it can't be fixed
with a new lint group, because `broken` is already in the `rustdoc` lint
group; there would need to be a way to nest groups somehow.
This also removes the early `return` so that the link will be generated
even though it gives a warning.
Refactor and fix intra-doc link diagnostics, and fix links to primitives
Closes https://github.com/rust-lang/rust/issues/76925, closes https://github.com/rust-lang/rust/issues/76693, closes https://github.com/rust-lang/rust/issues/76692.
Originally I only meant to fix#76925. But the hack with `has_primitive` was so bad it was easier to fix the primitive issues than to try and work around it.
Note that this still has one bug: `std::primitive::i32::MAX` does not resolve. However, this fixes the ICE so I'm fine with fixing the link in a later PR.
This is part of a series of refactors to make #76467 possible.

Stabilize intra-doc links
Fixes https://github.com/rust-lang/rust/issues/43466
Thanks to the great work of `@jyn514` in getting the [cross-crate reexport issue](https://github.com/rust-lang/rust/issues/65983) in intra-rustdoc links fixed, I think we're now in a position to stabilize this feature.
The tracking issue currently has two unresolved issues:
- <s>behavior around doc(hidden): This is fixed in https://github.com/rust-lang/rust/pull/73365, which is just waiting for CI and should land tomorrow. It's also a pretty niche bug so while I expect it to land soon I don't think we need to block stabilization on it anyway.</s>
- Non-identifier primitive types like slices: This was not a part of the original RFC anyway, and is a pretty niche use case
The feature itself, sans https://github.com/rust-lang/rust/issues/65983, has been shipped on nightly for three years now, with people using it on docs.rs. https://github.com/rust-lang/rust/issues/65983 itself is not an overwhelmingly central bit of functionality; the reason we elected to block stabilization on it was that back in 2017 it was not possible to fix the issue without some major refactorings of resolve, and we did not want to stabilize something that had such a potentially unfixable bug.
Given that we've fixed it, I see no reason to delay stabilization on this long awaited feature. It's possible that the latest patches have problems, however we _have_ done crater runs of some of the crucial parts. Furthermore, that's what the release trains are for, we will have a solid three months to let it ride the trains before it actually hits the stable compiler.

Now that `PrimTy::name()` exists, there's no need to carry around the
name of the primitive that failed to resolve. This removes the variants
special-casing primitives in favor of `NotResolved`.
- Remove `NoPrimitiveImpl` and `NoPrimitiveAssocItem`
- Remove hacky `has_primitive` check in `resolution_failure()`
- Fixup a couple tests that I forgot to `--bless` before
- Add `PrimTy::name` and `PrimTy::name_str`
- Use those new functions to distinguish between the name in scope and
the canonical name
- Fix diagnostics for primitive types
- Add tests for primitives
Previously, these were spread throughout the codebase. This had two
drawbacks:
1. It caused the fast path to be slower: even if a link resolved,
rustdoc would still perform various lookups for the error diagnostic.
2. It was inconsistent and didn't always give all diagnostics (https://github.com/rust-lang/rust/issues/76925)
Now, diagnostics only perform expensive lookups in the error case.
Additionally, the error handling is much more consistent, both in
wording and behavior.
- Remove `CannotHaveAssociatedItems`, `NotInScope`, `NoAssocItem`, and `NotAVariant`
in favor of the more general `NotResolved`
`resolution_failure` will now look up which of the four above
categories is relevant, instead of requiring the rest of the code to
be consistent and accurate in which it picked.
- Remove unnecessary lookups throughout the intra-doc link pass. These
are now done by `resolution_failure`.
+ Remove unnecessary `extra_fragment` argument to `variant_field()`;
it was only used to do lookups on failure.
+ Remove various lookups related to associated items
+ Remove distinction between 'not in scope' and 'no associated item'
- Don't perform unnecessary copies
- Remove unused variables and code
- Update tests
- Note why looking at other namespaces is still necessary
- 'has no inner item' -> 'contains no item'

Refactor intra doc link code
I got tired of `fold_item` being 500 lines long.
This is best reviewed one commit at a time with whitespace changes hidden.
There are no logic changes other than the last commit making a parameter checked by the caller instead of the callee.

Ignore rustc_private items from std docs
By ignoring rustc_private items for non local impl block,
this may fix#74672 and fix#75588 .
This might suppress #76529 if it is simple enough for backport.
