Add `imports_granularity = "Module"` to rustfmt.toml
This lets rustfmt split/merge imports, `Module` seems to be the most common style in clippy

[`arithmetic_side_effect`]: allow different types on the right hand side for `Wrapping<T>`
Fixes#11145
This lint has a list of allowed types, one of which is `Wrapping<T>`, but it was only actually allowed if the type on the right hand side was also `Wrapping<T>`, which meant that, for example, `Wrapping<u32> += u32` would still lint. It now allows binary ops involving `Wrapping<T>` regardless of the type on the rhs.
These impls have only existed since Rust 1.60.0, so that is probably why the lint was previously not handling this correctly

Fix bootstrap.py uname error
The x.py script fails with `ValueError: too many values to unpack (expected 3)` when uname -smp gives more than 3 words
The error I got:
```
❯ ./x check
Traceback (most recent call last):

This is because
```

Returns more than 3 space separated words.
Allow to have `-` in rustdoc-json test file name
I extracted this commit from https://github.com/rust-lang/rust/pull/113574.
When I added the test, it kept saying that the JSON file couldn't be found. After investigating for a while, I discovered that we were expecting files to always use `_`, which is quite bad. So I added support for `-` in file names.

Test simd-wide-sum for codegen error
This adds the necessary test infrastructure to "build-pass" codegen tests, for the purpose of doing that for a single revision of a codegen test. When mir-opts are tested, the output may vary from the usual, and maybe for positive reasons... but we don't necessarily want to output such bad LLVMIR that LLVM starts crashing on it.
Currently when enabling MIR opts at higher levels this LLVMIR is still emitted, but it was previously disabled for getting in mir-opt's way and as this new revision without `// [mir-opt3]build-pass` would make it more likely to, I would like to not see the testing for the actual results regress again just because it was bundled with an ICE check as well.
This fixes https://github.com/rust-lang/rust/issues/98016

Implement selection for `Unsize` for better coercion behavior
In order for much of coercion to succeed, we need to be able to deal with partial ambiguity of `Unsize` traits during selection. However, I pessimistically implemented selection in the new trait solver to just bail out with ambiguity if it was a built-in impl:
9227ff28af/compiler/rustc_trait_selection/src/solve/eval_ctxt/select.rs (L126)
This implements a proper "rematch" procedure for dealing with built-in `Unsize` goals, so that even if the goal is ambiguous, we are able to get nested obligations which are used in the coercion selection-like loop:
9227ff28af/compiler/rustc_hir_typeck/src/coercion.rs (L702)
Second commit just moves a `resolve_vars_if_possible` call to fix a bug where we weren't detecting a trait upcasting to occur.

Default to stable toolchain for metrics workflow
Metrics CI is failing because of a function that was stabilized in 1.70. So for some reason, it's trying to use an older toolchain i seems though I don't understand why it randomly started complaining about that.
Make fields of mir::Terminator public
When trying to use the RA crate, I am unable to access the fields in `hir_def::mir::Terminator`.
I don't see any reason, why these should be private, especially as the fields of `hir_def::mir::Statement` are `pub`.
I am not sure if the fields in `hir_def::mir::SwitchTargets` should be made `pub` too, but at least they are read-accessible via some public methods..
Sorry if I missed something, this is my first PR.
If someone says `x test rustdoc-js-std` explicitly on the command line, it's because they want to
run the tests. Give an error instead of doing nothing and reporting success.
...which seems not to be available on some platforms.
Or maybe it is under a different name but I don't want to deal with that
Instead, use two u64s. This isn't exactly the same, but we already have
some coverage of the packed u128 case in another test, so it's not
essential to have it here.
Coverage has two FFI functions for computing the hash of a byte string. One
takes a ptr/len pair, and the other takes a NUL-terminated C string.
But on closer inspection, the C string version is unnecessary. The calling-side
code converts a Rust `&str` into a C string, and the C++ code then immediately
turns it back into a ptr/len string before actually hashing it.
The function body immediately treats it as a slice anyway, so this just makes
it possible to call the hash function with arbitrary read-only byte slices.
