Remove i586-pc-windows-msvc
See [MCP 840](https://github.com/rust-lang/compiler-team/issues/840).
I left a specialized error message that should help users that hit this in the wild (for example, because they use it in their CI).
```
error: Error loading target specification: the `i586-pc-windows-msvc` target has been removed. Use the `i686-pc-windows-msvc` target instead.
Windows 10 (the minimum required OS version) requires a CPU baseline of at least i686 so you can safely switch. Run `rustc --print target-list` for a list of built-in targets
```
``@workingjubilee`` ``@calebzulawski`` fyi portable-simd uses this target in CI, if you wanna remove it already before this happens

Add minimal platform support documentation for powerpc-unknown-linux-gnuspe
Per https://github.com/rust-lang/rust/pull/137860#issuecomment-2692358259, add minimal platform support documentation, including a brief summary and links to more detailed information about this target.
The added documentation is minimal. This is somewhat similar to [powerpc-unknown-openbsd, which also has no target maintainer](https://doc.rust-lang.org/nightly/rustc/platform-support/powerpc-unknown-openbsd.html). The rest of the template is left to target maintainers.
I also updated powerpc-unknown-linux-muslspe platform support documentation and added link to powerpc-unknown-linux-gnuspe platform support documentation.

Wasmtime's `--wasm-features` and `--wasi-modules` flags have been renamed
since these docs were initially written.
Additionally, from my testing I don't believe `--wasm threads` is needed if
`--wasi threads` is passed already.

Update docs for default features of wasm targets
LLVM 20 enabled the `nontrapping-fptoint` and `bulk-memory` features by default, so this updates the corresponding documentation for the `wasm32-*` targets (which all point to `wasm32-unknown-unknown`).
Closes #137315 with a doc update for the doc part.

This commit removes the `avr-unknown-gnu-atmega328` target and replaces
it with a more generic `avr-none` variant that must be specialized with
the `-C target-cpu` flag (e.g. `-C target-cpu=atmega328p`).

Add cygwin target.
This PR simply adds cygwin target together with msys2 target, based on ````@ookiineko```` 's (the account has been deleted) [work](https://github.com/ookiineko-cygport/rust) on cygwin target. My full work is here: https://github.com/rust-lang/rust/compare/master...Berrysoft:rust:dev/cygwin
I have succeeded in building a new rustc for cygwin target, and eventually distributed a new version of [fish-shell](https://github.com/Berrysoft/fish-shell/releases) (rewritten by Rust) for MSYS2.
I will open a new PR to fix std if this PR is accepted.

i686-linux-android: increase CPU baseline to Pentium 4 (without an actual change
As per ``@maurer's`` [comment](https://github.com/rust-lang/rust/issues/136495#issuecomment-2648743078), this shouldn't actually change anything since we anyway add a bunch of extensions that bump things up way beyond Pentium 4. But Pentium 4 is consistent with the other i686 targets and I don't know enough about the exact sequence of CPU generations to be confident with more than this. ;)

Add amdgpu target
Add amdgpu target to rustc and enable the LLVM target.
Fix compiling `core` with the amdgpu:
The amdgpu backend makes heavy use of different address spaces. This
leads to situations, where a pointer in one addrspace needs to be casted
to a pointer in a different addrspace. `bitcast` is invalid for this
case, `addrspacecast` needs to be used.
Fix compilation failures that created bitcasts for such cases by
creating pointer casts (which creates an `addrspacecast` under the hood)
instead.
MCP: https://github.com/rust-lang/compiler-team/issues/823
Tracking issue: #135024
Kinda related to the original amdgpu tracking issue #51575 (though that one has been closed for a while).

Improve documentation when adding a new target
https://github.com/rust-lang/rust/pull/133631#issuecomment-2607877936 shows that it can be a bit difficult process-wise to add a new target.
I've added a bit of text to the docs, suggesting that users add the target defintion/spec first, and later work on `std` support.
I also found that we have two places where we document how to add a new target. I've linked these for now, but they should probably be merged somehow in the future.

Support QNX 7.1 with `io-sock`+libstd and QNX 8.0 (`no_std` only)
Changes of this pull request:
1. Refactor code for qnx nto targets to share more code in file `nto_qnx.rs`
1. Add support for an additional network stack on nto qnx 7.1.
QNX 7.1 supports two network stacks:
1. `io-pkt`, which is default
2. `io-sock`, which is optional on 7.1 but default in QNX 8.0
As one can see in the [io-sock migration notes](https://www.qnx.com/developers/docs/7.1/index.html#com.qnx.doc.neutrino.io_sock/topic/migrate_app.html), this changes the libc API in a way similar to e.g. linux-gnu vs. linux-musl.
This change adds a new target which has a different value for `target_env`, so that e.g. libc can distinguish between both APIs.
2. Add initial support for QNX 8.0, thanks to AkhilTThomas. As it turned out, the problem with forking many processes still exists in QNX 8.0. Because if this, we are now using it for any QNX version (i.e. not check for `target_env` anymore).

Update emscripten std tests
This disables a bunch of emscripten tests that test things emscripten doesn't support and re-enables a whole bunch of tests which now work just fine on emscripten.
Tested with `EMCC_CFLAGS="-s MAXIMUM_MEMORY=2GB" ./x.py test library/ --target wasm32-unknown-emscripten`.

fix(libtest): Deprecate '--logfile'
rust-lang/testing-devex-team#9 proposed changing the behavior of `--logfile`. The given reasons were:
(1) Bazel can't programmatically process stdout. This seems like a limitation in Bazel and we recommend focusing on that. If we look at the wider Rust ecosystem, Rustc and Cargo don't support any such mechanism and the Cargo team rejected having one. Expecting this in libtest when its not supported elsewhere seems too specialized.
(2) Tests that leak out non-programmatic output that intermixes with programmatic output. We acknowledge this is a problem to be evaluated but we need to make sure we are stepping back and gathering requirements, rather than assuming `--logfile` will fit the needs.
Independent of the motive, regarding using or changing `--logfile`
(1) Most ways to do it would be a breaking change, like if we respect any stable `--format`. As suggested above, we could specialize this to new `--format` values but that would be confusing for some values to apply but not others.
(2) Other ways of solving this add new features to lib`test` when we are instead wanting to limit the feature set it has to minimize the compatibility surface that has to be maintained and the burden it would put on third party harnesses which are a focus area. Examples include `--format compact` or a `--log-format` flag
(3) The existence of `--logfile` dates back quite a ways (https://github.com/rust-lang/rust/commit/5cc050b265509c19717e11e12dd785d8c73f5b11, rust-lang/rust#2127) and the history gives the
impression this more of slipped through rather than being an intended feature (see also
https://github.com/rust-lang/rust/pull/82350#discussion_r579732071). Deprecation would better match to how it has been treated. By deprecating this, we do not expect custom test harnesses (rust-lang/testing-devex-team#2) to implement this.
T-testing-devex held an FCP for deprecating in rust-lang/testing-devex-team#9 though according to
[RFC #3455](https://rust-lang.github.io/rfcs/3455-t-test.html), this is still subject to final approval from T-libs-api.

Improve check-cfg expected names diagnostic
This PR improves the check-cfg `allow-same-level` test by ~~normalizing it's output and by~~ adding more context to the test.
It also filters the well known cfgs from the `expected names are` note, as to reduce the size of the diagnostic. Users can still find the full list on the [rustc book](https://doc.rust-lang.org/nightly/rustc/check-cfg.html#well-known-names-and-values), which is reinforced for Cargo users by adding a note in the Cargo check-cfg specific section.
Fixes https://github.com/rust-lang/rust/issues/135995
