Remove under-used ImplPolarity enum
It doesn't make much sense to have an enum with only two possible values and to store it inside an `Option` in my opinion when you can do all the same with a simple boolean. I don't expect any chances, performance or RSS usage wise.

Support `download-ci-llvm` on NixOS
In particular, the CI built `libLLVM-*.so` needs to have `libz.so`
RPATHed so that binaries like `llvm-config` work at all.
Use correct span for structured suggestion
On structured suggestion for `let` -> `const` and `const` -> `let`, use
a proper `Span` and update tests to check the correct application.

Rustdoc: Fix macros 2.0 and built-in derives being shown at the wrong path
Fixes#74355
- ~~waiting on author + draft PR since my code ought to be cleaned up _w.r.t._ the way I avoid the `.unwrap()`s:~~
- ~~dummy items may avoid the first `?`,~~
- ~~but within the module traversal some tests did fail (hence the second `?`), meaning the crate did not possess the exact path of the containing module (`extern` / `impl` blocks maybe? I'll look into that).~~

Fix x.py install not working with relative prefix
The code powering `./x.py install` did not handle relative paths well: the installation script is executed inside a temporary directory, so all the relative paths specified in `config.toml` and in the `DESTDIR` environment variable were relative to that temporary directory. The original code fixed the problem for `config.toml` paths by canonicalizing the prefix, but breaking `DESTDIR`. https://github.com/rust-lang/rust/pull/80240 fixed the `DESTDIR` problem, but also regressed `config.toml` paths (#80683).
This PR refactors the installation code to generate paths that *in my understanding* are correct, adding comments in the meantime to explain what each step does. There was no documentation on why choices were made before, so my understanding could actually be wrong.
Regardless, executed `./x.py install` with various combinations of `config.toml` and `DESTDIR` paths, and everything seems to work according to my understanding. Still, I'd love if `@vext01` and `@yshui` could test these changes.

`@rustbot` modify labels: beta-nominated T-infra
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.
r? `@kinnison` if you have time, otherwise `@Manishearth`
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.
On structured suggestion for `let` -> `const` and `const` -> `let`, use
a proper `Span` and update tests to check the correct application.

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.
