HirIdification: rework Map
The next iteration of HirIdification (#57578).
- remove `NodeId` from `Entry`
- change `Map::map` to an `FxHashMap<HirId, Entry>`
- base the `NodeId` `Map` methods on `HirId` ones (reverses the current state)
- HirIdify `librustdoc` a little bit (some `NodeId` `Map` methods were converted to work on `HirId`s)
The second change might have performance implications, so I'd do a perf run to be sure it's fine; it simplifies the codebase and shouldn't have an impact as long as the `Map` searches are cached (which is now possible thanks to using `HirId`s).

This commit introduces an `ArgSource` enum that is lowered into the HIR
so that diagnostics can correctly refer to the argument pattern's
original name rather than the generated pattern.

I'd like to fix this but I don't know what to do.
I will work on later. Please let me know if you have any solutions.

This commit removes the check that disallows the `#[non_exhaustive]`
attribute from being placed on enum variants and removes the associated
tests.
Further, this commit lowers the visibility of enum variant constructors
when the variant is marked as non-exhaustive.
Type dependent defs wrappers
First of all, forgive me if something would seem lame to you or I offend some rule (although I tried to read through docs), this is my first PR.
Issue: https://github.com/rust-lang/rust/issues/59094
This PR adds 3 helper methods to `TypeckTables`:
* `opt_type_dependent_def`
* `opt_type_dependent_def_id`
* `type_dependent_def_id`
I didn't add `type_dependent_def` as was proposed in the issue simply because it wasn't used anywhere in the code. Only non-option wrapped`type_dependent_defs()[]` accesses were found in clippy which always called `def_id()` on result.
Speaking of clippy, should I open separate PR in its own repo, given it's used as submodule here?
Sry it took me so long, as I said I'm new here and I had tough week :).
This commit removes `CtorOf` from `Node::Ctor` as the parent of the
constructor can be determined by looking at the node's parent in the few
places where knowing this is necessary.
This commit makes two changes - separating the `NodeId` that identifies
an enum variant from the `NodeId` that identifies the variant's
constructor; and no longer creating a `NodeId` for `Struct`-style enum
variants and structs.
Separation of the variant id and variant constructor id will allow the
rest of RFC 2008 to be implemented by lowering the visibility of the
variant's constructor without lowering the visbility of the variant
itself.
No longer creating a `NodeId` for `Struct`-style enum variants and
structs mostly simplifies logic as previously this `NodeId` wasn't used.
There were various cases where the `NodeId` wouldn't be used unless
there was an unit or tuple struct or enum variant but not all uses of
this `NodeId` had that condition, by removing this `NodeId`, this must
be explicitly dealt with. This change mostly applied cleanly, but there
were one or two cases in name resolution and one case in type check
where the existing logic required a id for `Struct`-style enum variants
and structs.
middle: replace NodeId with HirId in AccessLevels
Pushing the limits of HirIdification (#57578).
Replaces `NodeId` with `HirId` in `middle::privacy::AccessLevels`. Actually this time I was more successful and cracked it; I probably tried to HirIdify too much at once when I attempted it last time ^^.

Refactor passes and pass execution to be more parallel
For `syntex_syntax` (with 16 threads and 8 cores):
- Cuts `misc checking 1` from `0.096s` to `0.08325s`.
- Cuts `misc checking 2` from `0.3575s` to `0.2545s`.
- Cuts `misc checking 3` from `0.34625s` to `0.21375s`.
- Cuts `wf checking` from `0.3085s` to `0.05025s`.
Reduces overall execution time for `syntex_syntax` (with 8 threads and cores) from `4.92s` to `4.34s`.

Cleanup: rename node_id_to_type(_opt)
Renames `node_id_to_type(_opt)` to `hir_id_to_type(_opt)`; this makes it clear we are dealing with HIR nodes and their IDs here.
In addition, a drive-by commit removing `ty::item_path::hir_path_str` (as requested by @eddyb).
Cosmetic improvements to doc comments
This has been factored out from https://github.com/rust-lang/rust/pull/58036 to only include changes to documentation comments (throughout the rustc codebase).
r? @steveklabnik
Once you're happy with this, maybe we could get it through with r=1, so it doesn't constantly get invalidated? (I'm not sure this will be an issue, but just in case...) Anyway, thanks for your advice so far!
Currently, the target of a use statement will be updated with
the visibility of the use statement itself (if the use statement was
visible).
This commit ensures that if the path to the target item is via another
use statement then that intermediate use statement will also have the
visibility updated like the target. This silences incorrect
`unreachable_pub` lints with inactionable suggestions.
Implement public/private dependency feature
Implements https://github.com/rust-lang/rust/issues/44663
The core implementation is done - however, there are a few issues that still need to be resolved:
- [x] The `EXTERNAL_PRIVATE_DEPENDENCY` lint currently does notthing when the `public_private_dependencies` is not enabled. Should mentioning the lint (in an `allow` or `deny` attribute) be an error if the feature is not enabled? (Resolved- the feature was removed)
- [x] Crates with the name `core` and `std` are always marked public, without the need to explcitily specify them on the command line. Is this what we want to do? Do we want to allow`no_std`/`no_core` crates to explicitly control this in some way? (Resolved - private crates are now explicitly specified)
- [x] Should I add additional UI tests? (Resolved - added more tests)
- [x] Does it make sense to be able to allow/deny the `EXTERNAL_PRIVATE_DEPENDENCY` on an individual item? (Resolved - this is implemented)
