Cleanup CodegenFnAttrFlags
- Rename `USED` to `USED_COMPILER` to better reflect its behavior.
- Reorder some items to group the used and allocator flags together
- Renumber them without gaps
rename internal panicking::try to catch_unwind
The public function is called `catch_unwind`, the intrinsic at some point got renamed to `catch_unwind` -- there's no reason to have the internal implementation of this still be called `try`, so let's rename it to match the rest.
additional edge cases tests for `path.rs` 🧪
This pull request adds a few new edge case tests to the `std::path` module. The new tests cover scenarios such as paths with only separators, non-ASCII and Unicode characters, embedded new lines, etc. Each new test is documented with some helpful in-line comments as well.

Use the fn_span when emitting function calls for better debug info.
This especially improves the developer experience for long chains of function calls that span multiple lines, which is common with builder patterns, chains of iterator/future combinators, etc.

document some -Z flags as living in the rustc-dev-guide
i was looking for these but didn't find them at first; add a breadcrumb so people know where to look
refactor `CanonicalVarKind`
it's unnecessary. I don't believe we'll ever need to store additional info shared by all `CanonicalVarKind`s.

std: sys: net: uefi: Implement TCP4 connect
- Implement TCP4 connect using EFI_TCP4_PROTOCOL.
- Tested on QEMU setup with connecting to TCP server on host.
Guarantee behavior of transmuting `Option::<T>::None` subject to NPO
In https://github.com/rust-lang/rust/pull/115333, we added a guarantee that transmuting from `[0u8; N]` to `Option<P>` is sound where `P` is a pointer type subject to the null pointer optimization (NPO). It would be useful to be able to guarantee the inverse - that a `None::<P>` value can be transmutes to an array and that will yield `[0u8; N]`.

Do not try to confirm non-dyn compatible method
See the comment I left in `compiler/rustc_hir_typeck/src/method/confirm.rs`.
If we have a receiver that does not deref to the `dyn Trait` we're assembling the method from, then we used to ICE, but that's something that is possible to encounter with arbitrary self types.

Dont walk into unsafe binders when emiting error for non-structural type match
Fixes#141422.
The other two binder-having types are also special cased here, unsurprisingly.

chore: fix typos in comment
## Fix Typos in Comments
This PR addresses several typos in the Rust standard library's documentation comments:
- In `library/std/src/sync/mpmc/list.rs`: Corrected "attemped" to "attempted"
- In `library/std/src/sys/thread_local/guard/key.rs`: Fixed "defering" to "deferring"
- In `library/std/src/sys/thread_local/guard/key.rs`: Fixed "futher" to "further"
These changes improve documentation readability and consistency without affecting any functional code.
make shared_helpers exe function work for both cygwin and non-cygwin hosts
On Cygwin, it needs to not append .exe, because /proc/self/exe (and therefore `std::env::current_exe`) does not include the .exe extension, breaking bootstrap's rustc wrapper. On hosts other than Cygwin, it *does* need to append .exe because the file really does have a .exe extension, and non-Cygwin hosts won't be doing the same filename rewriting that Cygwin does when looking for a file X but finding only X.exe in its place.
