Forbid tail calling intrinsics
There is only one intrinsic that can be called on stable, as far as I can find, (`transmute`). And in general tail calling intrinsics doesn't make much sense.
Alternative to rust-lang/rust#144815 (and thus closes rust-lang/rust#144815)
Fixes https://github.com/rust-lang/rust/issues/144806

Remove the omit_gdb_pretty_printer_section attribute
Disabling loading of pretty printers in the debugger itself is more reliable. Before this commit the .gdb_debug_scripts section couldn't be included in dylibs or rlibs as otherwise there is no way to disable the section anymore without recompiling the entire standard library.

dont assemble shadowed impl candidates
Fixes https://github.com/rust-lang/trait-system-refactor-initiative/issues/109.
I've originally intended to fix this by supporting lazy reevaluation when rerunning cycles. This ended up being really difficult, see https://github.com/lcnr/search_graph for my notes used while working on this. It is also insufficient for the `rayon-hang-2.rs` test as we end up with goals which we need to rerun for all combinations of provisional results. While landing such an optimization in the future may still be desirable, it is very difficult and insufficient to fix these hangs. Also see the relevant [zulip thread](https://rust-lang.zulipchat.com/#narrow/channel/364551-t-types.2Ftrait-system-refactor/topic/rustc-rayon.20hang/near/527850058).
I was previously opposed to avoiding assembling shadowed impls as it may prevent future improvements in this area, cc rust-lang/rust#141226. Going to track this and the reasoning behind it in https://github.com/rust-lang/trait-system-refactor-initiative/issues/226.

update fortanix tests
Firstly, as far as I can tell, no CI job actually runs any of the fortanix tests? Maybe I'm missing the job that runs these tests though?
In any case, the `assembly` tests now use `minicore`, meaning that they will run regardless of the host architecture (specifically, they will run during a standard PR CI build).
The run-make test is actually broken, and I'd propose to make it just `cargo build` rather than `cargo run`. We can have a separate test for actually running the program, if desired.
Also this test is subject to https://github.com/rust-lang/rust/issues/128733, so I'd like to re-evaluate what parts of the C/C++ compilation are actually required or useful.

[rustdoc] Display unsafe attrs with edition 2024 `unsafe()` wrappers.
Use Rust 2024 edition representation for unsafe attributes in rustdoc HTML:
- `#[no_mangle]` -> `#[unsafe(no_mangle)]`
- `#[export_name = "foo"]` -> `#[unsafe(export_name = "foo")]`
- `#[link_section = ".text"]` -> `#[unsafe(link_section = ".text")]`
The 2024 edition representation is used regardless of the crate's own edition. This ensures that Rustaceans don't have to learn the rules of an outdated edition (e.g. that `unsafe()` wasn't always necessary) in order to understand a crate's documentation.
After some looking through the `T-rustdoc` issues, I was not able to find an existing issue for this. Apologies if I missed it.

lolbinarycat:rustdoc-intra-doc-link-warn-more-54191, r=GuillaumeGomez
get rid of some false negatives in rustdoc::broken_intra_doc_links
rustdoc will not try to do intra-doc linking if the "path" of a link looks too much like a "real url".
however, only inline links (`[text](url)`) can actually contain a url, other types of links (reference links, shortcut links) contain a *reference* which is later resolved to an actual url.
the "path" in this case cannot be a url, and therefore it should not be skipped due to looking like a url.
fixes https://github.com/rust-lang/rust/issues/54191
to minimize the number of false positives that will be introduced, the following heuristic is used:
If there's no backticks, be lenient revert to old behavior.
This is to prevent churn by linting on stuff that isn't meant to be a link.
only shortcut links have simple enough syntax that they
are likely to be written accidentlly, collapsed and reference links
need 4 metachars, and reference links will not usually use
backticks in the reference name.
therefore, only shortcut syntax gets the lenient behavior.
here's a truth table for how link kinds that cannot be urls are handled:
| | is shortcut link | not shortcut link |
|--------------|--------------------|-------------------|
| has backtick | never ignore | never ignore |
| no backtick | ignore if url-like | never ignore |

Remove the witness type from coroutine *args* (without actually removing the type)
This does as much of rust-lang/rust#144157 as we can without having to break rust-lang/rust#143545 and/or introduce some better way of handling higher ranked assumptions.
Namely, it:
* Stalls coroutines based off of the *coroutine* type rather than the witness type.
* Reworks the dtorck constraint hack to not rely on the witness type.
* Removes the witness type from the args of the coroutine, eagerly creating the type for nested obligations when needed (auto/clone impls).
I'll experiment with actually removing the witness type in a follow-up.

fix: Match width of ascii and unicode secondary file start
The current [unicode secondary file start](https://github.com/rust-lang/rust/blob/64ca23b6235732fa61c0a2b957c5d7e591e7c972/compiler/rustc_errors/src/emitter.rs#L2991) is only three characters, whereas the ASCII variant and normal [file start](https://github.com/rust-lang/rust/blob/64ca23b6235732fa61c0a2b957c5d7e591e7c972/compiler/rustc_errors/src/emitter.rs#L2983-L2984) are four characters. This slight difference caused the paths following a Unicode secondary file start to not align with other structured elements.

Consider operator's span when computing binop expr span
When computing the span of a binop consisting of `lhs` and `rhs`, we previously just took the spans of `lhs.span.to(rhs.span)`. In the case that both `lhs` and `rhs` are both arguments to a macro, this can produce a wildly incorrect span.
To fix this, first compute the span between `lhs` and the binary operator, which will cause `lhs` to possibly be adjusted to a relevant macro metavar, and then compute that span extended to `rhs`, which will cause it to also be adjusted to a relevant macro metavar.
This coincidentally fixes a FIXME in `tests/ui/lint/wide_pointer_comparisons.rs` and suppresses a nonsense suggestion.

Fix linker-plugin-lto only doing thin lto
When rust provides LLVM bitcode files to lld and the bitcode contains
function summaries as used for thin lto, lld defaults to using thin lto.
This prevents some optimizations that are only applied for fat lto.
We solve this by not creating function summaries when fat lto is
enabled. The bitcode for the module is just directly written out.
An alternative solution would be to set the `ThinLTO=0` module flag to
signal lld to do fat lto.
The code in clang that sets this flag is here:
https://github.com/llvm/llvm-project/blob/560149b5e3c891c64899e9912e29467a69dc3a4c/clang/lib/CodeGen/BackendUtil.cpp#L1150
The code in LLVM that queries the flag and defaults to thin lto if not
set is here:
https://github.com/llvm/llvm-project/blob/e258bca9505f35e0a22cb213a305eea9b76d11ea/llvm/lib/Bitcode/Writer/BitcodeWriter.cpp#L4441-L4446

fix: Only "close the window" when its the last annotated file
While comparing the Unicode theme output of `rustc` and `annotate-snippets`, I found that `rustc` would ["close the window"](https://github.com/rust-lang/rust/blob/686bc1c5f9c06762b18082434c04d514acf6707e/compiler/rustc_errors/src/emitter.rs#L1025-L1027) (draw a `╰╴`), even though there were other annotated files that followed the current one. This PR makes it so the emitter will only "close the window" on the last annotated file.
Before:
```
error[E0624]: method `method` is private
╭▸ $DIR/close_window.rs:9:7
│
LL │ s.method();
╰╴ ━━━━━━ private method
│
⸬ $DIR/auxiliary/close_window.rs:3:5

LL │ fn method(&self) {}
╰╴ ──────────────── private method defined here
```
