Rollup merge of #79548 - CraftSpider:76998, r=jyn514
Show since when a function is const in stdlib

Fixes #76998

This makes it so that functions with the `#[rustc_const_stable()]` attribute now show from what version they were stably declared const, alongside what version they were declared stable. Example from `Result`:

Rollup merge of #79525 - jyn514:feature-gate-normalize, r=GuillaumeGomez
Add -Z normalize-docs and enable it for compiler docs

Works around https://github.com/rust-lang/rust/issues/79459 by only enabling normalization for the compiler itself (and anyone who opts-in on nightly). Eventually I want to remove this and enable normalization by default, but that's turned out to be [really hard](https://rust-lang.zulipchat.com/#narrow/stream/182449-t-compiler.2Fhelp/topic/How.20do.20I.20normalize.20projection.20types.20to.20a.20single.20type.3F/near/218125195).

This uses a command line option instead of a feature gate so it's easier to pass it to all crates at once. Theoretically it's better to use a feature gate instead so that it's easier for people to use on docs.rs, but I'm also not terribly concerned with how easy it to use a temporary hack.

Addresses https://github.com/rust-lang/rust/issues/77459.

b7ebc6b0c1 Auto merge of #76467 - jyn514:intra-link-self, r=Manishearth
Fix intra-doc links for `Self` on cross-crate items and primitives

- Remove the difference between `parent_item` and `current_item`; these
  should never have been different.
- Remove `current_item` from `resolve` and `variant_field` so that
  `Self` is only substituted in one place at the very start.
- Resolve the current item as a `DefId`, not a `HirId`. This is what
  actually fixed the bug.

Hacks:
- `clean` uses `TypedefItem` when it _really_ should be
  `AssociatedTypeItem`. I tried fixing this without success and hacked
  around it instead (see comments)
- This second-guesses the `to_string()` impl since it wants
  fully-qualified paths. Possibly there's a better way to do this.

  this is a larger task than I want to take on right now.

af780e569d Auto merge of #78380 - bstrie:rm-old-num-const-from-tests, r=jyn514
Update tests to remove old numeric constants

Part of #68490.

Care has been taken to leave the old consts where appropriate, for testing backcompat regressions, module shadowing, etc. The intrinsics docs were accidentally referring to some methods on f64 as std::f64, which I changed due to being contrary with how we normally disambiguate the shadow module from the primitive. In one other place I changed std::u8 to std::ops since it was just testing path handling in macros.

For places which have legitimate uses of the old consts, deprecated attributes have been optimistically inserted. Although currently unnecessary, they exist to emphasize to any future deprecation effort the necessity of these specific symbols and prevent them from being accidentally removed.

Extend doc keyword feature by allowing any ident

Part of #51315.

As suggested by ``@danielhenrymantilla`` in [this comment](https://github.com/rust-lang/rust/issues/51315#issuecomment-733879934), this PR extends `#[doc(keyword = "...")]` to allow any ident to be used as keyword. The final goal is to allow (proc-)macro crates' owners to write documentation of the keywords they might introduce.

ec039bd075 Auto merge of #79336 - camelid:rename-feature-oibit-to-auto, r=oli-obk
Rename `optin_builtin_traits` to `auto_traits`

They were originally called "opt-in, built-in traits" (OIBITs), but
people realized that the name was too confusing and a mouthful, and so
they were renamed to just "auto traits". The feature flag's name wasn't
updated, though, so that's what this PR does.

There are some other spots in the compiler that still refer to OIBITs,
but I don't think changing those now is worth it since they are internal
and not particularly relevant to this PR.

Also see <https://rust-lang.zulipchat.com/#narrow/stream/131828-t-compiler/topic/opt-in.2C.20built-in.20traits.20(auto.20traits).20feature.20name>.

Fix links to extern types in rustdoc (fixes #78777)

 Fixes #78777.
The initial fix we tried was:
```diff

             Res::PrimTy(prim) => Some(
                 self.resolve_primitive_associated_item(prim, ns, module_id, item_name, item_str),
             ),
-            Res::Def(DefKind::Struct | DefKind::Union | DefKind::Enum | DefKind::TyAlias, did) => {
+            Res::Def(kind, did) if kind.ns() == Some(Namespace::TypeNS) => {
                 debug!("looking for associated item named {} for item {:?}", item_name, did);
+
                 // Checks if item_name belongs to `impl SomeItem`
                 let assoc_item = cx
                     .tcx
```

However, this caused traits to be matched, resulting in a panic when `resolve_associated_trait_item` is called further down in this function.

This PR also adds an error message for that panic. Currently it will look something like:
```rust
thread 'rustc' panicked at 'Not a type: DefIndex(8624)', compiler/rustc_metadata/src/rmeta/decoder.rs:951:32
```
I wasn't sure how to get a better debug output than `DefIndex(...)`, and am open to suggestions.

fc4ca55291 Add from_def_id_and_kind reducing duplication in rustdoc
- Add `Item::from_hir_id_and_kind` convenience wrapper
- Make name parameter mandatory

  `tcx.opt_item_name` doesn't handle renames, so this is necessary
  for any item that could be renamed, which is almost all of them.

- Override visibilities to be `Inherited` for enum variants

  `tcx.visibility` returns the effective visibility, not the visibility
  that was written in the source code. `pub enum E { A, B }` always has
  public variants `A` and `B`, so there's no sense printing `pub` again.

- Don't duplicate handling of `Visibility::Crate`

  Instead, represent it as just another `Restricted` path.

6c28ffbef3 Use DefPath for clean::Visibility, not clean::Path
Visibility needs much less information than a full path, since modules
can never have generics. This allows constructing a Visibility from only
a DefId.

Note that this means that paths are now normalized to their DefPath.
In other words, `pub(self)` or `pub(super)` now always shows `pub(in
path)` instead of preserving the original text.

Rollup merge of #78678 - Nemo157:doc-cfg-w-traits, r=jyn514,GuillaumeGomez
Add tests and improve rendering of cfgs on traits

Shows the additional features required to get the trait implementation, suppressing any already shown on the current page. One interesting effect from this is if you have a cfg-ed type, implementing a cfg-ed trait (so the implementation depends on both cfgs), you will get the inverted pair of cfgs shown on each page:

![image](https://user-images.githubusercontent.com/81079/97904671-207bdc00-1d41-11eb-8144-707e8017d2b6.png)

The hidden items on the trait implementation also now get the correct cfgs displayed on them.
