Rollup merge of #114813 - RalfJung:fpu-control, r=Amanieu
explain why we can mutate the FPU control word

This is usually not allowed (see https://github.com/rust-lang/stdarch/pull/1454), but here we have a special case.

Rollup merge of #114412 - RalfJung:libc-symbols, r=pnkfelix
document our assumptions about symbols provided by the libc

LLVM makes assumptions about `memcmp`, `memmove`, and `memset` that go beyond what the C standard guarantees -- see https://reviews.llvm.org/D86993. Since we use LLVM, we are inheriting these assumptions.

With https://github.com/rust-lang/rust/pull/114382 we are also making a similar assumption about `memcmp`, so I added that to the list.

Fixes https://github.com/rust-lang/unsafe-code-guidelines/issues/426.

Rollup merge of #113510 - ink-feather-org:const_ptr_transmute_docs, r=RalfJung
Document soundness of Integer -> Pointer -> Integer conversions in `const` contexts.

see this [zulip thread](https://rust-lang.zulipchat.com/#narrow/stream/146212-t-compiler.2Fconst-eval/topic/Soundness.20of.20Integer.20-.3E.20Pointer.20-.3E.20Integer.20conversions)

r? `@RalfJung`

With this slice `Iterator`'s should be able to be made const once the const Trait reimplementation is done.

Add `fmease` to rustdoc review rotations

`@fmease` asked me if it was okay for them to be part of the rustdoc review rotation. Since they are already reviewing a lot of rustdoc PRs, I think it's fine to add them to the rotation.

What do you think `@rust-lang/rustdoc` ?

Self-explanatory, we should avoid ICEs when the feature gate is not enabled. Continue to ICE when the feature gate *is* enabled, though.

3141177995 Copy most of tests/run-coverage into tests/coverage-map/status-quo
The output of these tests is too complicated to comfortably verify by hand, but
we can still use them to observe changes to the underlying mappings produced by
codegen/LLVM.

If these tests fail due to non-coverage changes (e.g. in HIR-to-MIR lowering or
MIR optimizations), it should usually be OK to just `--bless` them, as long as
the `run-coverage` test suite still works.

004db4728b Add test suite coverage-map to test coverage mappings emitted by LLVM
We compile each test file to LLVM IR assembly, and then pass that IR to a
dedicated program that can decode LLVM coverage maps and print them in a more
human-readable format. We can then check that output against known-good
snapshots.

This test suite has some advantages over the existing `run-coverage` tests:

- We can test coverage instrumentation without needing to run target binaries.

- We can observe subtle improvements/regressions in the underlying coverage
mappings that don't make a visible difference to coverage reports.

9c609ae158 Auto merge of #115467 - compiler-errors:assoc-ty-object-safety, r=oli-obk
Do not require associated types with Self: Sized to uphold bounds when confirming object candidate

RPITITs and associated types that have `Self: Sized` bounds are opted out of the `dyn Trait` well-formedness check that happens during confirmation. This ensures that we can actually *use* `dyn Trait`s that have associated types that, e.g., have GATs and RPITITs and other naughty things as long as those are opted-out of object safety via a `Self: Sized` bound.

Fixes #115464

This seems like a natural part of https://github.com/rust-lang/rust/pull/112319#issuecomment-1592574451, and I don't think needs re-litigation.

This PR adds an `#[allow(...)]` attribute hep suggestion along with the implied by suggestion:

  note: `-W dead-code` implied by `-W unused`
+ help: to override `-W unused` add `#[allow(dead_code)]`

This PR also adds the `OnceHelp` lint level (similar to `OnceNote`) to only put the help message one time, like the implied note.

Encode DepKind as u16

The derived Encodable/Decodable impls serialize/deserialize as a varint, which results in a lot of code size around the encoding/decoding of these types which isn't justified: The full range of values here is rather small but doesn't quite fit in to a `u8`. Growing _all_ serialized `DepKind` to 2 bytes costs us on average 1% size in the incr comp dep graph, which I plan to recoup in https://github.com/rust-lang/rust/pull/110050 by taking advantage of the unused bits in all the serialized `DepKind`.

Use std::io::Error::is_interrupted everywhere

In https://github.com/rust-lang/rust/pull/115228 I introduced this helper and started using it, this PR uses it to replace all applicable uses of `std::io::Error::kind`. The justification is the same; for whatever reason LLVM totally flops optimizing `Error::kind` so it's nice to use it less.

FYI ``@mkroening`` I swear the hermit changes look good, but I was so sure about the previous PR.

Reference uplifted clippy lints' rustc name in the release notes

I updated to Rust 1.72.0, got a new warning from rustc, wanted to read more about it, so I went to RELEASES.md and searched for the new lint's name as shown in the warning I got.

I found no results because the relevant entry in RELEASES only contained the lint's old Clippy name, not its new rustc name.

This adds the rustc name for lints so that someone doing the same thing I did will have more success.

Some of the uplifted lints didn't have a name change, so I didn't add the rustc name as a search for it will succeed.
