This version was released as part of a security fix for Wasmtime. The
fix didn't change Cranelift though, so this commit is not strictly
necessary, but also doesn't hurt.

Improve niche placement by trying two strategies and picking the better result

Fixes #104807
Fixes #105371

Determining which sort order is better requires calculating the struct size (so we can calculate the niche offset). But that in turn depends on the field order, so happens after sorting. So the simple way to solve that is to run the whole thing twice and pick the better result.

1st commit is just code motion, the meat is in the later ones.

Rollup merge of #110965 - compiler-errors:anon-lt-dupe-oops, r=cjgillot
Don't duplicate anonymous lifetimes for async fn in traits

`record_lifetime_params_for_async` needs to be called outside of the scope of the function, or else it'll end up collecting anonymous lifetimes twice (those on the function and those within the `AnonymousCreateParameter` rib). This matches how `record_lifetime_params_for_async` is being used for functions with bodies below.

This fixes (partially) #110963 when the lifetimes are late-bound, but does not do so when the lifetimes are early-bound (as seen from the known-bug that I added).

Rollup merge of #110958 - compiler-errors:stdlib-refinement, r=cuviper
Make sure that some stdlib method signatures aren't accidental refinements

In the process of implementing https://rust-lang.github.io/rfcs/3245-refined-impls.html, I found a bunch of stdlib implementations that accidentally "refined" their method signatures by dropping  (unnecessary) bounds.

This isn't currently a problem, but may become one if/when method  signature refining is stabilized in the future. Shouldn't hurt to make these signatures a bit more accurate anyways.

NOTE (just to be clear lol): This does not affect behavior at all, since we don't actually take advantage of refined implementations yet!

include source error for LoadLibraryExW

In #107595, we added retry behavior for LoadLibraryExW on Windows. If it fails we do not print the underlying error that Windows returned. This made #110889 a little harder to debug.

In this PR I am adding the source error in the message if it is available.

Rollup merge of #110614 - compiler-errors:new-solver-overflow-response, r=lcnr
Clear response values for overflow in new solver

When we have an overflow, return a trivial query response. This fixes an ICE with the code described in #110544:

```rust
trait Trait {}

struct W<T>(T);

impl<T, U> Trait for W<(W<T>, W<U>)>
where
    W<T>: Trait,
    W<U>: Trait,
{}

fn impls<T: Trait>() {}

fn main() {
    impls::<W<_>>()
}
```

Where, while proving `W<?0>: Trait`, we overflow but still apply the query response of `?0 = (W<?1>, W<?2>)`. Then while re-processing the query to validate that our evaluation result was stable, we get a different query response that looks like `?1 = (W<?3>, W<?4>), ?2 = (W<?5>, W<?6>)`, and so we trigger the ICE.

Also, by returning a trivial query response we also avoid the infinite-loop/OOM behavior of the old solver.

run-make test: using single quotes to not trigger the shell

This test got added in #110801.

I'm no expert on Makefiles, but IIUC this command is passed to the shell, which usually tries to execute commands specified in between backticks in double-quoted strings.

Using single quotes should fix this, I think. (Note: Waiting for CI to test this, since I only have a web browser available right now).

Rollup merge of #110921 - JohnBobbo96:rustc_arena_nonnull, r=Nilstrieb
Use `NonNull::new_unchecked` and `NonNull::len` in `rustc_arena`.

This avoids a few extra dereferences as well as an `unwrap`.

According to the docs for [`NonNull::len`](https://doc.rust-lang.org/std/ptr/struct.NonNull.html#method.len) this also ensures that:

> This function is safe, even when the non-null raw slice cannot be dereferenced to a slice because the pointer does not have a valid address.

I am also fairly sure that the `unwrap` is unneeded in this case, as the docs for [`Box::into_raw`](https://doc.rust-lang.org/std/boxed/struct.Box.html#method.into_raw) also state:

> Consumes the Box, returning a wrapped raw pointer.
**The pointer will be properly aligned and non-null.**

Rollup merge of #110917 - Be-ing:whole_archive_with_staticlib_fix, r=petrochenkov
only error combining +whole-archive and +bundle for rlibs

Fixes https://github.com/rust-lang/rust/issues/110912

Checking `flavor == RlibFlavor::Normal` was accidentally lost in 601fc8b36b
https://github.com/rust-lang/rust/pull/105601

That caused combining +whole-archive and +bundle link modifiers on non-rlib crates to fail with a confusing error message saying that combination is unstable for rlibs. In particular, this caused the build to fail when +whole-archive was used on staticlib crates, even though +whole-archive effectively does nothing on non-bin crates because the final linker invocation is left to an external build system.

Rollup merge of #110877 - compiler-errors:binop-err, r=cjgillot
Provide better type hints when a type doesn't support a binary operator

For example, when checking whether `vec![A] == vec![A]` holds, we first evaluate the LHS's ty, then probe for any `PartialEq` implementations for that. If none is found, we report an error by evaluating `Vec<A>: PartialEq<?0>` for fulfillment errors, but the RHS is not yet evaluated and remains an inference variable `?0`!

To fix this, we evaluate the RHS and equate it to that RHS infer var `?0`, so that we are able to provide more detailed fulfillment errors for why `Vec<A>: PartialEq<Vec<A>>` doesn't hold (namely, the nested obligation `A: PartialEq<A>` doesn't hold).

Update awscli

The Windows GitHub Actions image just updated to pip 23.1.1 which broke the PyYaml installer in the current AWS CLI mirror.  It now requires setuptools, wheel, and Cython to be installed manually.  This updates to include that, as well as updating the versions of all the packages. This also now uses python3 on macOS since python2 doesn't work with the newer versions.

I have only tested that these install correctly, but not that they work correctly.

Pietro mentioned that we should just switch to aws cli 2, which I agree is probably the better solution. I'm posting this PR in case it helps unblock CI.

43a78029b4 Auto merge of #110837 - scottmcm:offset-for-add, r=compiler-errors
Use MIR's `Offset` for pointer `add` too

~~Status: draft while waiting for #110822 to land, since this is built atop that.~~
~~r? `@ghost~~`

Canonical Rust code has mostly moved to `add`/`sub` on pointers, which take `usize`, instead of `offset` which takes `isize`.  (And, relatedly, when `sub_ptr` was added it turned out it replaced every single in-tree use of `offset_from`, because `usize` is just so much more useful than `isize` in Rust.)

Unfortunately, `intrinsics::offset` could only accept `*const` and `isize`, so there's a *huge* amount of type conversions back and forth being done.  They're identity conversions in the backend, but still end up producing quite a lot of unhelpful MIR.

This PR changes `intrinsics::offset` to accept `*const` *and* `*mut` along with `isize` *and* `usize`.  Conveniently, the backends and CTFE already handle this, since MIR's `BinOp::Offset` [already supports all four combinations](adaac6b166/compiler/rustc_const_eval/src/transform/validate.rs (L523-L528)).

To demonstrate the difference, I added some `mir-opt/pre-codegen/` tests around slice indexing.  Here's the difference to `[T]::get_mut`, since it uses `<*mut _>::add` internally:
```diff

23e91d4d73 Remove some unnecessary derives.
I was curious about how many `Encodable`/`Decodable` derives we have.
Some grepping revealed that it's over 500 of each, but the number of
`Encodable` ones was higher, which was weird. Most of the
`Encodable`-only ones were in `hir.rs`. This commit removes them all,
plus some other unnecessary derives in that file and others that I found
via trial and error.
