It's either "profile-guided" or "profiled-guided" and I think it'sw the former. :)

Fix a couple Emscripten tests
This fixes a couple Emscripten tests where the correct fix is more or less obvious. A couple UI tests are still broken with this PR:
- `tests/ui/abi/numbers-arithmetic/return-float.rs` (#136197)
- `tests/ui/no_std/no-std-unwind-binary.rs` (haven't debugged yet)
- `tests/ui/test-attrs/test-passed.rs` (haven't debugged this either)

Clean up uses of the unstable `dwarf_version` option
- Consolidate calculation of the effective value.
- Check the target `DebuginfoKind` instead of using `is_like_msvc`.
- Add the tracking issue to the unstable book page for this feature.

Match Ergonomics 2024: update edition 2024 behavior of feature gates
This updates the edition 2024 behavior of the feature gates `ref_pat_eat_one_layer_2024_structural` and `ref_pat_eat_one_layer_2024` to correspond to the left and right typing rules compared [here](https://nadrieril.github.io/typing-rust-patterns/?compare=true&opts2=AQEBAAABAQABAgIAAQEBAAEBAAABAAA%3D&opts1=AQEBAgEBAQEBAgIAAAAAAAAAAAAAAAA%3D&mode=rules&do_cmp=true&ty_d=3&style=SequentBindingMode), respectively. I'll implement the proposed new behavior for editions ≤ 2021 in another PR.
The tests are split up a bit awkwardly for practical reasons, but I've added new tests from 3 places:
- I got tests for where the typing rules differ from the "Compare" tab of the page linked above. These had to be split up based on where the errors are emitted and how rustfixable they are, so they've ended up in different files to keep tidy. Within each file, though, the order of the tests matches the order the typing differences appear in that comparison (as of when this was written).
- I used [this other comparison](https://nadrieril.github.io/typing-rust-patterns/?q=%5B%26mut+%26%28mut+x%29%5D%3A+%26mut+%5B%26CT%5D&compare=true&opts2=AQEBAgABAQEBAgIAAQEBAAEBAAABAAA%3D&opts1=AQEBAgEBAQEBAgIAAAAAAAAAAAAAAAA%3D&mode=compare&do_cmp=true&ty_d=3&style=SequentBindingMode) to test the `Deref(EatInner, FallbackToOuter)` rule of the left/"structural"/eat-inner ruleset. These are all in `well-typed-edition-2024.rs`.
- I added some select tests for cases where the new typing rules differ from current stable Rust. I had to be pickier about what I included here, but I tried to make sure each typing rule got some coverage. That said, my approach for these tests was a bit ad-hoc, so I may have missed something.

[rustdoc] Add sans-serif font setting
Fixes https://github.com/rust-lang/rust/issues/52449.
This PR adds a new setting introducing the possibility to switch to a sans-serif font (`Fira Sans`) for the text.
Can be tested [here](https://rustdoc.crud.net/imperio/sans-serif/std/index.html).

Simplify and consolidate the way we handle construct `OutlivesEnvironment` for lexical region resolution
This is best reviewed commit-by-commit. I tried to consolidate the API for lexical region resolution *first*, then change the API when it was finally behind a single surface.

miri: optimize zeroed alloc
When allocating zero-initialized memory in MIR interpretation, rustc allocates zeroed memory, marks it as initialized and then re-zeroes it. Remove the last step.
I don't expect this to have much of an effect on performance normally, but in my case in which I'm creating a large allocation via mmap it gets in the way.

Set st_fstype of stat on Solaris and Illumos OSes

This reduces the size of both these args, and of path segments,
so should measurably help with memory use.

tests: Port `translation` to rmake.rs
Part of #121876.
This PR partially supersedes #129011 and is co-authored with `@Oneirical.`
## Summary
This PR ports `tests/run-make/translation` to rmake.rs. Notable changes from the Makefile version include:
- We now actually fail if the rustc invocations fail... The Makefile did not have `SHELL=/bin/bash -o pipefail`, so all the piped rustc invocations to grep vacuously succeeded, even if the broken ftl test case actually regressed over time and ICEs on current master.
- That test case is converted to assert it fails with a FIXME backlinking to #135817.
- The test coverage is expanded to not ignore windows. Instead, the test now uses symlink capability detection to gate test execution.
- Added some backlinks to relevant tracking issues and the initial translation infra implementation PR.
## Review advice
Best reviewed commit-by-commit.

Merge `PatKind::Path` into `PatKind::Expr`
Follow-up to #134228
We always had a duplication where `Path`s could be represented as `PatKind::Path` or `PatKind::Lit(ExprKind::Path)`. We had to handle both everywhere, and still do after #134228, so I'm removing it now.

This way, adding a bunch of comments to the JS files won't make
rustdoc slower.

Previously it may have been possible for different completion items to
produce colliding hashes, not because of the hash but because of how
the items were serialized into byte streams for hashing. See #19071
for details.
The chances of that happening were low, if it was actually possible at
all. Nevertheless, this commit ensures that it definitely can't happen.
This commit uses a handful of techniques used to fix this, but they all
boil down to "ensure this could be re-parsed". If it's possible to parse
to recreate the original item, then by construction there is no chance
of two different items getting serialized to identical byte streams.
