very minor cleanups
- add `must_use` to `early_error_no_abort`
this was already being used at its only callsite, but this ensures that new code remembers to use it if it's called in the future. found this while investigating https://github.com/rust-lang/rust/issues/110090.
- remove outdated and incorrect comment in `builder.rs`. `doc_rust_lang_org_channel` doesn't exist in rustdoc, it gets it from an env var instead: https://github.com/rust-lang/rust/blob/b275d2c30b6e88cc48747f349f7137076d450658/src/librustdoc/clean/utils.rs#L569-L573

Only depend on CFG_VERSION in rustc_interface
This avoids having to rebuild the whole compiler on each commit when `omit-git-hash = false`.
cc https://github.com/rust-lang/rust/issues/76720 - this won't fix it, and I'm not suggesting we turn this on by default, but it will make it less painful for people who do have `omit-git-hash` on as a workaround.

Error message all end up passing into a function as an `impl
Into<{D,Subd}iagnosticMessage>`. If an error message is creatd as
`&format("...")` that means we allocate a string (in the `format!`
call), then take a reference, and then clone (allocating again) the
reference to produce the `{D,Subd}iagnosticMessage`, which is silly.
This commit removes the leading `&` from a lot of these cases. This
means the original `String` is moved into the
`{D,Subd}iagnosticMessage`, avoiding the double allocations. This
requires changing some function argument types from `&str` to `String`
(when all arguments are `String`) or `impl
Into<{D,Subd}iagnosticMessage>` (when some arguments are `String` and
some are `&str`).

Introduce `DynSend` and `DynSync` auto trait for parallel compiler
part of parallel-rustc #101566
This PR introduces `DynSend / DynSync` trait and `FromDyn / IntoDyn` structure in rustc_data_structure::marker. `FromDyn` can dynamically check data structures for thread safety when switching to parallel environments (such as calling `par_for_each_in`). This happens only when `-Z threads > 1` so it doesn't affect single-threaded mode's compile efficiency.

Migrate `mir_transform` to translatable diagnostics

Add deployment-target --print flag for Apple targets
This is very useful for crates that need to know what the Apple OS deployment target is for their build scripts or inside of a build environment. Right now, the defaults just get copy/pasted around the ecosystem since they've been stable for so long. But with #104385 in progress, that won't be true anymore and everything will need to move. Ideally whenever it happens again, this could be less painful as everything can ask the compiler what its default is instead.
To show examples of the copy/paste proliferation, here's some crates and/or apps that do:
- [cc](https://github.com/rust-lang/cc-rs/pull/708/files), Soon
- [mac-notification-sys](https://github.com/h4llow3En/mac-notification-sys/pull/46/files#diff-d0d98998092552a1d3259338c2c71e118a5b8343dd4703c0c7f552ada7f9cb42R10-R12)
- [PyO3](https://github.com/PyO3/maturin/blob/ccb02d1aa1cc41e82a3572a3c8b35cace15f3e78/src/target.rs#L755-L758)
- [Anki](https://github.com/ankitects/anki/blob/613b5c1034cc9943f3f68d818ae22b2e0acec877/build/runner/src/bundle/artifacts.rs#L49-L54)
- [jsc-rs](https://github.com/Brooooooklyn/jsc-rs/blob/37767267568fb2de62fc441473e7d158dd980520/xtask/src/build.rs#L402-L405)

Make the BUG_REPORT_URL configurable by tools
This greatly simplifies how hard it is to set a custom bug report url; previously tools had to copy
the entire hook implementation.
I haven't changed clippy in case they want to make the change upstream instead of the subtree, but
I'm happy to do so here if the maintainers want - cc ````@rust-lang/clippy````
Fixes https://github.com/rust-lang/rust/issues/109486.

- Switch clippy to the new hook
This also adds a `extra_info` callback so clippy can include its own version number, which differs
from rustc's.
- Call `install_ice_hook` in rustfmt

Fluent, with all the icu4x it brings in, takes quite some time to
compile. `fluent_messages!` is only needed in further downstream rustc
crates, but is blocking more upstream crates like `rustc_index`. By
splitting it out, we allow `rustc_macros` to be compiled earlier, which
speeds up `x check compiler` by about 5 seconds (and even more after the
needless dependency on `serde_json` is removed from
`rustc_data_structures`).

Stabilize IsTerminal
FCP completed in https://github.com/rust-lang/rust/issues/98070 .

Before, rustdoc was missing `-C passes=list` and the "Available options"
header.
Making these match allows testing that they match exactly.

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`.

It partially expands crate attributes before the main expansion pass (without modifying the crate), and the produced preliminary crate attribute list is used for querying a few attributes that are required very early.
Crate-level cfg attributes are then expanded normally during the main expansion pass, like attributes on any other nodes.

Extend `CodegenBackend` trait with a function returning the translation
resources from the codegen backend, which can be added to the complete
list of resources provided to the emitter.

Instead of loading the Fluent resources for every crate in
`rustc_error_messages`, each crate generates typed identifiers for its
own diagnostics and creates a static which are pulled together in the
`rustc_driver` crate and provided to the diagnostic emitter.

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.

fixes https://github.com/rust-lang/miri/issues/2778
this was introduced in https://github.com/rust-lang/rust/pull/104645, so this PR reverts the flag-part and uses an env var instead.
