Make all download functions need only Config, not Builder
This also adds a new `mod download` instead of scattering the download code across `config.rs` and `native.rs`.
This is the simplest and also most bit-rotty part of https://github.com/rust-lang/rust/pull/102282. Opening it earlier so it's not mixed in with behavior changes and to avoid rebase hell.
cc https://github.com/rust-lang/rust/issues/94829 (which nows has the hackmd linked).
r? `@Mark-Simulacrum`
Add `delay_span_bug` to `AttrWrapper::take_for_recovery`
`take_for_recovery` should only be used for recovery (when we should already have an error), so using `delay_span_bug` seems appropriate.
cc `@Aaron1011` (you've added the `FIXME` that this pr fixes)
Enable profiler in dist-s390x-linux
Build the profiler runtime to allow using -C profile-generate and -C instrument-coverage on s390x-linux.
I've verified in a local build that the runtime builds and the profiler is working fine on the platform.
Document `Path::parent` behavior around relative paths
A relative path with just one component will return `Some("")` as its parent, which wasn't clear to me from the documentation.
The parent of `""` is `None`, which was missing from the documentation as well.
Add a few known-bug tests
The labels of these tests should be changed from `S-bug-has-mcve` to `S-bug-has-test` once this is merged.

I couldn't reproduce the failures in #101962 and #100772 (so either these have started passing, or I didn't repro properly), so leaving those out for now.
#102065 was a bit more complicated, since it uses `rustc_private` and I didn't want to mess with that.
llvm: dwo only emitted when object code emitted
Fixes#103932.
`CompiledModule` should not think a DWARF object was emitted when a bitcode-only compilation has happened, this can confuse archive file creation (which expects to create an archive containing non-existent dwo files).

ci: Upgrade dist-x86_64-netbsd to NetBSD 9.0
This is another step in toolchain upgrades for LLVM 16, which will need at least GCC 7.1.
Our previous NetBSD 8.0 cross-toolchain used its system GCC 5.5. While there are newer versions available in pkgsrc, I could not get those working for cross-compilation. Upgrading to NetBSD 9.0 gets us GCC 7.4, which is sufficient for now.
This will affect the compatibility of the build we ship for `x86_64-unknown-netbsd`, but others may still build their own from source if that is needed. It is expected that NetBSD 8 will reach EOL soon anyway, approximately one month after 10 is released, but there is no firm date for that.
Change the way libunwind is linked for *-windows-gnullvm targets
I have no idea why previous way works for `x86_64-fortanix-unknown-sgx` (assuming it actually works...) but not for `gnullvm`. It fails when linking libtest during Rust build (unless somebody adds `RUSTFLAGS='-Clinkarg=-lunwind'`).
Also fixes exception handling on AArch64.

`@rustbot` modify labels: rollup
This was originally a part of https://github.com/rust-lang/rust/pull/100316.
However, extracting it to a seperate PR should help with any extra
testing that might be needed.

Use `derive_const` and rm manual StructuralEq impl
This does not change any semantics of the impl except for the const stability. It should be fine because trait methods and const bounds can never be used in stable without enabling `const_trait_impl`.

Add small clarification around using pointers derived from references
r? `@RalfJung`
One question about your example from https://github.com/rust-lang/libs-team/issues/122: at what point does UB arise? If writing 0 does not cause UB and the reference `x` is never read or written to (explicitly or implicitly by being wrapped in another data structure) after the call to `foo`, does UB only arise when dropping the value? I don't really get that since I thought references were always supposed to point to valid data?
```rust
fn foo(x: &mut NonZeroI32) {
let ptr = x as *mut NonZeroI32;
unsafe { ptr.cast::<i32>().write(0); } // no UB here
// What now? x is considered garbage when?
}
```
Fix missing reexports' doc comments
Fixes#81893.
The issue was that an import directly "links" to the target without the intermediate imports. Unfortunately, to fix this bug we need to go through them one by one. To do so, I take the import path direct parent (so `b` in `a:🅱️:c`) and then look for `c` into it.
