Implement round.ps and round.pd SSE4.1 intrinsics
I had forgotten them.
I also increased the coverage of rounding tests to make sure the rounding direction is working as expected (e.g. test `1.25`, `1.5`, `1.75`...).
Treat thread-local statics on main thread as static roots for leakage analysis
Miri currently treats allocations as leaked if they're only referenced in thread-local statics. For threads other than the main thread, this is correct, since the thread can terminate before the program does, but references in the main thread's locals should be treated as living for the duration of the program since the thread lives for the duration of the program.
This PR adds thread-local statics and TLS keys as "static roots" for leakage analysis, but does not yet bless the example program from #2881. See https://github.com/rust-lang/miri/issues/2881#issuecomment-1585666652Closes#2881
Deny more `~const` trait bounds

Add `std:#️⃣:{DefaultHasher, RandomState}` exports (needs FCP)
This implements rust-lang/libs-team#267 to move the libstd hasher types to `std::hash` where they belong, instead of `std::collections::hash_map`.
<details><summary>The below no longer applies, but is kept for clarity.</summary>
This is a small refactor for #27242, which moves the definitions of `RandomState` and `DefaultHasher` into `std::hash`, but in a way that won't be noticed in the public API.
I've opened rust-lang/libs-team#267 as a formal ACP to move these directly into the root of `std::hash`, but for now, they're at least separated out from the collections code in a way that will make moving that around easier.
I decided to simply copy the rustdoc for `std::hash` from `core::hash` since I think it would be ideal for the two to diverge longer-term, especially if the ACP is accepted. However, I would be willing to factor them out into a common markdown document if that's preferred.

Switch `fuchsia-test-runner.py` to `ffx product`
The subcommand `ffx product-bundle` has been removed, and replaced with the subcommand `ffx product`. This changes `fuchsia-test-runner.py` to use it to download the SDK and product bundle for the latest release of Fuchsia.

On method chain expression failure, look for missing method in earlier segments of the chain
This PR tries to fix the issue: https://github.com/rust-lang/rust/issues/115222
As suggested by `@estebank` , I did the following:
1. Add new test `tests/ui/structs/method-chain-expression-failure.rs`
2. In `compiler/rusct_hir_tycheck/src/method/suggest.rs`
walking up the method chain and calling `probe_for_name` with the method name. But the call fails to return `Ok`.
enable unstable feature on `x clean [PATH]`
Since https://github.com/rust-lang/rust/pull/111076 enables unstable cargo feature (`public-dependency`), we need to ensure that unstable features are enabled before reading libstd Cargo.toml.

bump few ICU4X leftover deps

There no strict version dependencies between some crates, so yoke was 0.7.2, but yoke-derive left with 0.7.1, same with zerofrom, zerofrom-derive, zerovec, zerovec-derive; drops synstructure 0.12* dependency, less syn 1.* users left.
rustdoc-json: Fix test so it actually checks things
After #111427, no item has a `kind` field, so these assertions could never fail. Instead, assert that those two items arn't present.

Clarify UB in `get_unchecked(_mut)`
Inspired by #116915, it was unclear to me what exactly "out-of-bounds index" means in `get_unchecked`.
One could [potentially](https://rust.godbolt.org/z/hxM764orW) interpret it that `get_unchecked` is just another way to write `offset`, but I think `get_unchecked(len)` is supposed to be UB even though `.offet(len)` is well-defined (as is `.get_unchecked(..len)`), so write that more directly in the docs.
**libs-api folks**: Can you confirm whether this is what you expect this to mean? And is the situation any different for `<*const [T]>::get_unchecked`?

Emit #[inline] on derive(Debug)
While working on https://github.com/rust-lang/rust/pull/116583 I noticed that the `cross_crate_inlinable` query identifies a lot of derived `Debug` impls as a MIR body that's little more than a call, which suggests they may be a good candidate for `#[inline]`. So here I've implemented that change specifically.
It seems to provide a nice improvement to build times.
Since https://github.com/rust-lang/rust/pull/111076 enables
unstable cargo feature (`public-dependency`), we need to ensure
that unstable features are enabled before reading libstd Cargo.toml.

check config file before prompts on `x setup`
First 2 commit moves the check of configuration existence to the first step of `x setup`. And then followed by a prompt that allows devs to decide whether to continue with the configuration override or exit bootstrap.
Closes#110471
I can revert the last commit if needed. Maybe it's just me, but I feel it's better to have those tags capitalized. If you think otherwise, please let me know so that I can revert.
Allow configuring the parent GitHub repository
The git integration in build_helper hardcoded `rust-lang/rust` as the parent GitHub repository, and `master` as the branch name. This works great for `rust-lang/rust`, but causes problems in downstream forks like Ferrocene whenever those functions are invoked (like `./x fmt`).
In `src/stage0.json` there was already a configuration key for the name of the nightly branch, but it wasn't used by build_helper. This PR adds the `github_repository` key to the file, and requires both values to be passed to build_helper whenever a git function is called. This will allow downstream forks to tweak the values.
generator layout: ignore fake borrows
fixes#117059
We emit fake shallow borrows in case the scrutinee place uses a `Deref` and there is a match guard. This is necessary to prevent the match guard from mutating the scrutinee: fab1054e17/compiler/rustc_mir_build/src/build/matches/mod.rs (L1250-L1265)
These fake borrows end up impacting the generator witness computation in `mir_generator_witnesses`, which causes the issue in #117059. This PR now completely ignores fake borrows during this computation. This is sound as thse are always removed after analysis and the actual computation of the generator layout happens afterwards.
Only the second commit impacts behavior, and could be backported by itself.
