we will add an explicit incompatibility of softfloat and vector feature
in rutsc s390x-unknown-none-softfloat target specification.
Therefore we need to disable vector intrinsics here to be able to compile
core for this target.
library/std: Rename `ON_BROKEN_PIPE_FLAG_USED` to `ON_BROKEN_PIPE_USED`
This commit is a pure internal rename and does not change any functionality.
The `FLAG_` part of `ON_BROKEN_PIPE_FLAG_USED` comes from that the compiler flag `-Zon-broken-pipe=...` is used to enable the feature.
Remove the `FLAG_` part so the name works both for the current compiler flag `-Zon-broken-pipe=...` and for the upcoming [Externally Implementable Item `#[std::io::on_broken_pipe]`](https://github.com/rust-lang/rust/pull/150591) PR. This makes the diff of that PR smaller.
The local variable name `sigpipe_attr_specified` comes from way back when the feature was controlled with an `fn main()` attribute called `#[unix_sigpipe = "..."]`. Rename that too.

Fix set_times_nofollow for directory on windows
Fix issue from:
https://github.com/rust-lang/rust/issues/147455#issuecomment-3841311858
old code `opts.write(true)` on Windows requests `GENERIC_WRITE` access, replace with `opts.access_mode(c::FILE_WRITE_ATTRIBUTES)` to get minimal permission.

fN::BITS constants for feature float_bits_const
Also enables the feature for compiler_builtins as otherwise this causes a warning and conflicts with the Float extension trait.
---
Implementation for rust-lang/rust#151073
Feature flag: `#![feature(float_bits_const)]`
Note that this is likely to conflict with some extension traits, as it has with compiler builtins. However, assuming correct values for the constants, they are either `u32`, the same type, which should not cause a problem (as shown by enabling the feature for compiler_builtins), or a different type (e.g. `usize`), which should cause a compiler error. Either way this should never change behaviour unless the extension trait implemented an incorrect value.
Also note that it doesn't seem to be possible to put multiple unstable attributes on an item, so `f128::BITS` and `f16::BITS` are gated behind the feature flags for those primitives, rather than `#![feature(float_bits_const)]`
Fix uninitialized UEFI globals in tests
Export globals via a `doc(hidden)` module. In test code, use the globals from `realstd` so that they are properly initialized.

Add new `byte_value` and `char_value` methods to `proc_macro::Literal`
Part of https://github.com/rust-lang/rust/issues/136652.
It adds two more methods to get unescaped `u8` and `char` from `proc_macro::Literal`.

GVN: Elide more intermediate transmutes
We already skipped intermediate steps like `u32` or `i32` that support any (initialized) value.
This extends that to also allow skipping intermediate steps whose values are a superset of either the source or destination type. Most importantly, that means that `usize` → `NonZeroUsize` → `ptr::Alignment` and `ptr::Alignment` → `NonZeroUsize` → `usize` can skip the middle because `NonZeroUsize` is a superset of `Alignment`.
Then `Alignment::as_usize` is updated to take advantage of that and let us remove some more locals in a few places.

This commit introduces initial, unstable support for Unix domain sockets
(UDS) on Windows, behind the `windows_unix_domain_sockets` feature gate
Added types:
- `std::os::windows::net::SocketAddr`: represents a UDS address with support
for pathname addresses (abstract and unnamed are parsed but not yet fully
supported).
- `std::os::windows::net::UnixListener`: server-side UDS listener.
- `std::os::windows::net::UnixStream`: client/server stream for UDS.
Key features:
- Binding and connecting using filesystem paths.
- Basic I/O via `Read`/`Write`.
- Address querying (`local_addr`, `peer_addr`).
- Non-blocking mode, timeouts, and socket duplication.
- Includes basic test coverage for smoke, echo, path length, and bind reuse.
