This adjusts the `rustdoc` trait impl collection path to preserve `Deref` impls
from other crates. This adds a first pass to map all of the `Deref` type to
target edges and then recursively preserves all targets.
handle generic trait methods in coverage-report tests
also make the generic function pattern more specific and remove the extra $ that fails the matching.

Don't panic when an external crate can't be resolved
This isn't actually a bug, it can occur when rustdoc tries to resolve a
crate that isn't used in the main code.
Fixes#72381.

Make sure rust-call errors occur correctly for traits
Fixes#79669
Adds trait method resolution to the error, and adds UI tests to ensure it doesn't happen again. Opening as draft because I'm getting weird link errors from unrelated code on my machine, and want to see what CI thinks.
rustc_parse: Better spans for synthesized token streams
I think using the nonterminal span for synthesizing its tokens is a better approximation than using `DUMMY_SP` or the attribute span like #79472 did in `expand.rs`.

Properly handle primitive disambiguators in rustdoc

Is there a way to test that the generated intra-doc link is what I expect?
MIR Inline is incompatible with coverage
Fixes: #80060
Fixed by disabling inlining if `-Zinstrument-coverage` is set.
The PR also adds additional use cases to the coverage test for doctests.

Remove useless doc_alias feature gate
As `@jyn514` rightfully noted in https://github.com/rust-lang/rust/pull/80686 , this feature is no more. Therefore, cleanup time!

make sure that promoteds which fail to evaluate in dead const code behave correctly
https://github.com/rust-lang/rust/pull/80243 showed that we'll have to live with these kinds of failing promoteds for a while, so let's make sure we have a test that covers them.
Add check for `[T;N]`/`usize` mismatch in astconv
Helps clarify the issue in #80506
by adding a specific check for mismatches between [T;N] and usize.

Add note to non-exhaustive match on reference to empty
Rust prints "type `&A` is non-empty" even is A is empty.
This is the intended behavior, but can be confusing.
This commit adds a note to non-exhaustive pattern errors if they are a
reference to something uninhabited.
I did not add tests to check that the note is not shown for
non-references or inhabited references, because this is already done
in other tests.
Maybe the added test is superfluous, because
`always-inhabited-union-ref` already checks for this case.
This does not handle &&Void or &&&void etc. I could add those as special
cases as well and ignore people who need quadruple
references.
Fixes#78123
Allow references to interior mutable data behind a feature gate
supercedes #80373 by simply not checking for interior mutability on borrows of locals that have `StorageDead` and thus can never be leaked to the final value of the constant

Rustdoc: only report broken ref-style links once
This PR assigns the markdown `LinkType` to each parsed link and passes this information into the link collector.
If a link can't be resolved in `resolve_with_disambiguator`, the failure is cached for the link types where we only want to report the error once (namely `Shortcut` and `Reference`).

Add suggestion for "ignore" doc code block

rustdoc DocFragment rework
Kind of a follow-up of #80119.
A few things are happening in this PR. I'm not sure about the impact on perf though so I'm very interested about that too (if the perf is worse, then we can just close this PR).
The idea here is mostly about reducing the memory usage by relying even more on `Symbol` instead of `String`. The only issue is that `DocFragment` has 3 modifications performed on it:
1. Unindenting
2. Collapsing similar comments into one
3. "Beautifying" (weird JS-like comments handling).
To do so, I saved the information about unindent and the "collapse" is now on-demand (which is why I'm not sure the perf will be better, it has to be run multiple times...).
