Start using `windows sys` for Windows FFI bindings in std
Switch to using windows-sys for FFI. In order to avoid some currently contentious issues, this uses windows-bindgen to generate a smaller set of bindings instead of using the full crate.
Unlike the windows-sys crate, the generated bindings uses `*mut c_void` for handle types instead of `isize`. This to sidestep opsem concerns about mixing pointer types and integers between languages. Note that `SOCKET` remains defined as an integer but instead of being a usize, it's changed to fit the [standard library definition](a41fc00eaf/library/std/src/os/windows/raw.rs (L12-L16)):
```rust
#[cfg(target_pointer_width = "32")]
pub type SOCKET = u32;
#[cfg(target_pointer_width = "64")]
pub type SOCKET = u64;
```
The generated bindings also customizes the `#[link]` imports. I hope to switch to using raw-dylib but I don't want to tie that too closely with the switch to windows-sys.
---
Changes outside of the bindings are, for the most part, fairly minimal (e.g. some differences in `*mut` vs. `*const` or a few types differ). One issue is that our own bindings sometimes mix in higher level types, like `BorrowedHandle`. This is pretty adhoc though.
Introduce `AliasKind::Inherent` for inherent associated types
Allows us to check (possibly generic) inherent associated types for well-formedness.
Type inference now also works properly.

Mark s390x condition code register as clobbered in inline assembly
Various s390x instructions (arithmetic operations, logical operations, comparisons, etc. see also "Condition Codes" section in [z/Architecture Reference Summary](https://www.ibm.com/support/pages/zarchitecture-reference-summary)) modify condition code register `cc`, but AFAIK there is currently no way to mark it as clobbered in `asm!`.
`cc` register definition in LLVM:

This PR also updates asm_experimental_arch docs in the unstable-book to mention s390x registers.

Remove `identity_future` from stdlib
This function/lang_item was introduced in #104321 as a temporary workaround of future lowering. The usage and need for it went away in #104833.
After a bootstrap update, the function itself can be removed from `std`.
STD support for PSVita
This PR adds std support for `armv7-sony-vita-newlibeabihf` target.
The work here is fairly similar to #95897, just for a different target platform.

Make `(try_)subst_and_normalize_erasing_regions` take `EarlyBinder`
Changes `subst_and_normalize_erasing_regions` and `try_subst_and_normalize_erasing_regions` to take `EarlyBinder<T>` instead of `T`.
(related to #105779)
This was suggested by `@BoxyUwU` in https://github.com/rust-lang/rust/pull/107753#discussion_r1105828139. After changing `type_of` to return `EarlyBinder`, there were several places where the binder was immediately skipped to call `tcx.subst_and_normalize_erasing_regions`, only for the binder to be reconstructed inside of that method.

I chose to re-do the work rather than rebase the onto the large changes since the original PR. If it's preferred I can instead force-push the original PR to this version.

Fix the test directories suggested by `./x.py suggest`
It seems that these paths were correct when #106249 was being written, but since then #106458 has been merged (moving `src/test/` to `tests/`), making the tool's suggestions incorrect.
Remove aws cli install.
All runner images have the AWS CLI 2 installed, so there isn't a really strong reason to install our own version anymore.
The version we were installing was 1.27.122. The runner images currently have 2.11.x (the exact version varies by image).
I do not have the means to really test if the new version has any issues. I looked at all the `aws` commands, and none of them seem to be doing anything unusual. The page at https://docs.aws.amazon.com/cli/latest/userguide/cliv2-migration-changes.html contains a list of all the breaking changes, and I didn't see anything that looked important.
Make the BUG_REPORT_URL configurable by tools
This greatly simplifies how hard it is to set a custom bug report url; previously tools had to copy
the entire hook implementation.
I haven't changed clippy in case they want to make the change upstream instead of the subtree, but
I'm happy to do so here if the maintainers want - cc ````@rust-lang/clippy````

Update the version of musl used on `*-linux-musl` targets to 1.2.3
Update the version of musl used on our Linux musl targets from 1.1.24 to 1.2.3 as proposed in rust-lang/compiler-team#572. musl 1.2.3 is the latest version of musl and supports the same range of Linux kernels as the 1.1 series. As such, it does not affect the minimum supported version of Linux for any of the musl targets.
One of the major musl 1.2 features is support for [time64](https://musl.libc.org/time64.html). This support is both source and ABI compatible with programs built against musl 1.1 and so updating the musl version for these targets should not cause Rust programs to fail to run or compile (a [crater run](https://github.com/rust-lang/rust/pull/107129#issuecomment-1407196104) has been completed which demonstrates this for the `i686-unknown-linux-musl` target).
Once this change reaches stable, the `libc` crate will then be able to [update their definitions to support 64-bit time](https://github.com/rust-lang/libc/pull/3068), matching the default musl 1.2 APIs exactly.
Fixes#91178
Mark `ErrorGuaranteed` constructor as deprecated so people don't use it
You should never ever ever ever ever ever ever ever ever ever ever ever ever ever ever ever ever use this function unless you know what you're doing, so make it harder to accidentally use it!
Alternatives are to change the name to sound scarier, make it `unsafe` (though it's not really a soundness thing), or work on deeper refactors to make it private.

Issue 109502 follow up, remove unnecessary Vec::new() from compile_test()
As mentioned in comment on PR #110773 , adding a separate function to pass the test passes into the `dump-mir` is a bit nicer
rustdoc-search: add slices and arrays to index
This indexes them as primitives with generics, so `slice<u32>` is how you search for `[u32]`, and `array<u32>` for `[u32; 1]`. A future commit will desugar the square bracket syntax to search both arrays and slices at once.
Stabilize raw-dylib, link_ordinal, import_name_type and -Cdlltool
This stabilizes the `raw-dylib` feature (#58713) for all architectures (i.e., `x86` as it is already stable for all other architectures).
Changes:
* Permit the use of the `raw-dylib` link kind for x86, the `link_ordinal` attribute and the `import_name_type` key for the `link` attribute.
* Mark the `raw_dylib` feature as stable.
* Stabilized the `-Zdlltool` argument as `-Cdlltool`.
* Note the path to `dlltool` if invoking it failed (we don't need to do this if `dlltool` returns an error since it prints its path in the error message).
* Adds tests for `-Cdlltool`.
* Adds tests for being unable to find the dlltool executable, and dlltool failing.
* Fixes a bug where we were checking the exit code of dlltool to see if it failed, but dlltool always returns 0 (indicating success), so instead we need to check if anything was written to `stderr`.
NOTE: As previously noted (https://github.com/rust-lang/rust/pull/104218#issuecomment-1315895618) using dlltool within rustc is temporary, but this is not the first time that Rust has added a temporary tool use and argument: https://github.com/rust-lang/rust/pull/104218#issuecomment-1318720482

Reduce MIR dump file count for MIR-opt tests
As referenced in issue #109502 , mir-opt tests previously used the -Zdump-mir=all flag, which generates very large output. This PR only dumps the passes under test, greatly reducing dump output.
