rustdoc: Fix invalid suggestions on ambiguous intra doc links v2
Fixes https://github.com/rust-lang/rust/issues/108653.
This is another approach to fixing the same issue. This time, we keep the computed information around instead of re-computing it.
Strangely enough, the order for ambiguities seem to have been changed. Not an issue but it creates a lot of diff...
So which version do you prefer?
r? `@notriddle`
`-Cdebuginfo=1` was never line tables only and
can't be due to backwards compatibility issues.
This was clarified and an option for line tables only
was added. Additionally an option for line info
directives only was added, which is well needed for
some targets. The debug info options should now
behave the same as clang's debug info options.
rustdoc: Fix ICE for intra-doc link on intermediate re-export
Fixes https://github.com/rust-lang/rust/issues/109282.
This PR is based on #109266 as it includes its commit to make this work.
`@petrochenkov:` It was exactly as you predicted, adding the `DefId` to the attributes fixed the error for intermediate re-exports as well. Thanks a lot!

Add `-Z time-passes-format` to allow specifying a JSON output for `-Z time-passes`
This adds back the `-Z time` option as that is useful for [my rustc benchmark tool](https://github.com/Zoxc/rcb), reverting https://github.com/rust-lang/rust/pull/102725. It now uses nanoseconds and bytes as the units so it is renamed to `time-precise`.

Implement -Zlink-directives=yes/no
`-Zlink-directives=no` will ignored `#[link]` directives while compiling a crate, so nothing is emitted into the crate's metadata. The assumption is that the build system already knows about the crate's native dependencies and can provide them at link time without these directives.
This is another way to address issue # #70093, which is currently addressed by `-Zlink-native-libraries` (implemented in #70095). The latter is implemented at link time, which has the effect of ignoring `#[link]` in *every* crate. This makes it a very large hammer as it requires all native dependencies to be known to the build system to be at all usable, including those in sysroot libraries. I think this means its effectively unused, and definitely under-used.
Being able to control this on a crate-by-crate basis should make it much easier to apply when needed.
I'm not sure if we need both mechanisms, but we can decide that later.

[breaking change] Remove a rustdoc back compat warning
This warning was introduced in https://github.com/rust-lang/rust/pull/62855 for users who use `rustdoc` directly on proc macro crates (instead of using `cargo doc`) without passing `--crate-type proc-macro` (which `cargo doc` passed automatically).

remove unstable `pick_stable_methods_before_any_unstable` flag
This flag was only added in #90329 in case there was any issue with the impl so that it would be easy to tell nightly users to use the flag to disable the new logic to fix their code. It's now been enabled for two years and also I can't find any issues corresponding to this new functionality? This flag made it way harder to understand how this code works so it would be nice to remove it and simplify what's going on.

Including unstable lints in the lint group produces unintuitive behavior
on stable (see #106289). Meanwhile, if we only included unstable lints
on nightly and not on stable, we could end up with confusing bugs that
were hard to compare across versions of Rust that lacked code changes.
I think that only including stable lints in `rustdoc::all`, no matter
the release channel, is the most intuitive option. Users can then
control unstable lints individually, which is reasonable since they have
to enable the feature gates individually anyway.
Most tests involving save-analysis were removed, but I kept a few where
the `-Zsave-analysis` was an add-on to the main thing being tested,
rather than the main thing being tested.
For `x.py install`, the `rust-analysis` target has been removed.
For `x.py dist`, the `rust-analysis` target has been kept in a
degenerate form: it just produces a single file `reduced.json`
indicating that save-analysis has been removed. This is necessary for
rustup to keep working.
Closes#43606.
Introduce `-Zterminal-urls` to use OSC8 for error codes
Terminals supporting the OSC8 Hyperlink Extension can support inline anchors where the text is user defineable but clicking on it opens a browser to a specified URLs, just like `<a href="URL">` does in HTML.

Recognize all bells and whistles that LLVM's XRay pass is capable of.
The always/never settings are a bit dumb without attributes but they're
still there. The default instruction count is chosen by the compiler,
not LLVM pass. We'll do it later.
Use stable metric for const eval limit instead of current terminator-based logic
This patch adds a `MirPass` that inserts a new MIR instruction `ConstEvalCounter` to any loops and function calls in the CFG. This instruction is used during Const Eval to count against the `const_eval_limit`, and emit the `StepLimitReached` error, replacing the current logic which uses Terminators only.
The new method of counting loops and function calls should be more stable across compiler versions (i.e., not cause crates that compiled successfully before, to no longer compile when changes to the MIR generation/optimization are made).
Also see: #103877
Emit a single error for contiguous sequences of unknown tokens
Closes#106101
On encountering a sequence of identical source characters which are unknown tokens, note the amount of subsequent characters and advance past them silently. The old behavior was to emit an error and 'help' note for every single one.
