91f87bc9bc Set CMAKE_SYSTEM_NAME when cross-compiling
Configure CMAKE_SYSTEM_NAME when cross-compiling in `configure_cmake`,
to tell CMake about target system. Previously this was done only for
LLVM step and now applies more generally to steps using cmake.

a0c290f951 Auto merge of #75212 - JulianKnodt:array_map, r=LukasKalbertodt
Add `array` lang item and `[T; N]::map(f: FnMut(T) -> S)`

This introduces an `array` lang item so functions can be defined on top of `[T; N]`. This was previously not done because const-generics was not complete enough to allow for this. Now it is in a state that is usable enough to start adding functions.

The function added is a monadic (I think?) map from `[T; N] -> [S; N]`. Until transmute can function on arrays, it also allocates an extra temporary array, but this can be removed at some point.

d69b0997d7 Auto merge of #75431 - ehuss:platform-support, r=Mark-Simulacrum
Move platform support to the rustc book.

This moves the [Platform Support](https://forge.rust-lang.org/release/platform-support.html) page from the forge to the rustc book. There are several reasons for doing this:

* The forge is not really oriented towards end-users (it mostly contains infrastructure, governance and policy, internal team pages, etc.). This platform support page is useful to user to know which targets are supported.
* This page can now be updated in-sync with any PRs that add or remove a target, or change its status.
* This is now automatically checked on CI to verify the list does not get out of sync. Currently it only checks the presence/absence of an entry, but more sophisticated checks could be added in the future.

I'm not 100% certain this is the best location, but I think it fits. I'd like to see the rustc guide continue to grow, including things like linking information and more platform-specific details.

Rollup merge of #75189 - kawamuray:bugfix-wasi-append, r=KodrAus
Fix wasi::fs::OpenOptions to imply write when append is on

This PR fixes a bug in `OpenOptions` of `wasi` platform that it currently doesn't imply write mode when only `append` is enabled.
As explained in the [doc of OpenOptions#append](https://doc.rust-lang.org/std/fs/struct.OpenOptions.html#method.append), calling `.append(true)` should imply `.write(true)` as well.

## Reproduce

Given below simple Rust program:

```rust
use std::fs::OpenOptions;
use std::io::Write;

fn main() {
    let mut file = OpenOptions::new()
        .write(true)
        .create(true)
        .open("foo.txt")
        .unwrap();
    writeln!(file, "abc").unwrap();
}
```

it can successfully compiled into wasm and execute by `wasmtime` runtime:

```sh
$ rustc --target wasm32-wasi write.rs
$ ~/wasmtime/target/debug/wasmtime run --dir=. write.wasm
$ cat foo.txt
abc
```

However when I change `.write(true)` to `.append(true)`, it fails to execute by the error "Capabilities insufficient":

```sh
$ ~/wasmtime/target/debug/wasmtime run --dir=. append.wasm
thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Os { code: 76, kind: Other, message: "Capabilities insufficient" }', append.rs:10:5
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
Error: failed to run main module `append.wasm`
...
```

This is because of lacking "rights" on the opened file:

```sh
$ RUST_LOG=trace ~/wasmtime/target/debug/wasmtime run --dir=. append.wasm 2>&1 | grep validate_rights
 TRACE wasi_common::entry                                  >      | validate_rights failed: required rights = HandleRights { base: fd_write (0x40), inheriting: empty (0x0) }; actual rights = HandleRights { base: fd_seek|fd_fdstat_set_flags|fd_sync|fd_tell|fd_advise|fd_filestat_set_times|poll_fd_readwrite (0x88000bc), inheriting: empty (0x0) }
```

d4593af78f Change registered "program name" for -Cllvm-args usage messages
While debugging a codegen issue, I tried adding LLVM options with
the rustc -Cllvm-args option, and was confused by the error and usage
messaging.

The LLVM "program name" argument is set to "rustc", and command line
error messages make it look like invalid arguments are "rustc"
arguments, not LLVM.

I changed this argument so error messages and the "-help" usage feedback
is easier to understand and react to. (Clang does something similar.)

Put panic code path from `copy_from_slice` into cold function

The previous `assert_eq` generated quite some code, which is especially problematic when this call is inlined. This commit also slightly improves the panic message from:

    assertion failed: `(left == right)`
      left: `3`,
     right: `2`: destination and source slices have different lengths

...to:

    source slice length (2) does not match destination slice length (3)

You can see the code bloat in assembly [here](https://rust.godbolt.org/z/74a3qo).

Miri: improve spans of required_const failures

In https://github.com/rust-lang/rust/pull/75339 I added a loop evaluating all consts required by a function body. Unfortunately, if one of their evaluations fails, then the span used for that was that of the first statement in the function body, which happened to work form some existing test but is not sensible in general.

This PR changes it to point to the whole function instead, which is at least not wrong.
