59ae5eba7e Auto merge of #132514 - Zalathar:print-target-cpus, r=jieyouxu 
Port most of `--print=target-cpus` to Rust

The logic and formatting needed by `--print=target-cpus` has historically been carried out in C++ code. Originally it used `printf` to write directly to the console, but later it switched over to writing to a `std::ostringstream` and then passing its buffer to a callback function pointer.

This PR replaces that C++ code with a very simple function that writes a list of CPU names to a `&RustString`, with the rest of the logic and formatting being handled by ordinary safe Rust code.

compiler: Continue introducing rustc_abi to the compiler

Some crates have not heard of rustc_abi before, so arrange introductions.

Encourage some crates to go further and leave rustc_target behind: it was no good for them.

Rollup merge of #132540 - compiler-errors:gc, r=calebcartwright 
Do not format generic consts

We introduced **nightly support** for generic const items in #113522, but formatting of consts was not modified. Making them format *correctly* is hard, so let's just bail formatting them so we don't accidentally strip their generics and where clauses. This is essentially no-op formatting for generic const items.

Rollup merge of #132503 - RalfJung:const-hash-map, r=Amanieu 
better test for const HashMap; remove const_hash leftovers

The existing `const_with_hasher` test is kind of silly since the HashMap it constructs can never contain any elements. So this adjusts the test to construct a usable HashMap, which is a bit non-trivial since the default hash builder cannot be built in `const`. `BuildHasherDefault::new()` helps but is unstable (https://github.com/rust-lang/rust/issues/123197), so we also have a test that does not involve that type.

The second commit removes the last remnants of https://github.com/rust-lang/rust/issues/104061, since they aren't actually useful -- without const traits, you can't do any hashing in `const`.

coverage: Regression test for inlining into an uninstrumented crate

Regression test for #132395, after I was able to figure out a simple way to reproduce it. See also #132436.

In addition to confirming that there is no ICE, this test also demonstrates that the affected code is undercounted, because executing the inlined copy doesn't increment coverage counters.

Implement `From<&mut {slice}>` for `Box/Rc/Arc<{slice}>`

ACP: https://github.com/rust-lang/libs-team/issues/424

New API:

```rust
impl<T: Clone> From<&mut [T]> for Box<[T]>
impl From<&mut str> for Box<str>
impl From<&mut CStr> for Box<CStr>
impl From<&mut OsStr> for Box<OsStr>
impl From<&mut Path> for Box<Path>

impl<T: Clone> From<&mut [T]> for Rc<[T]>
impl From<&mut str> for Rc<str>
impl From<&mut CStr> for Rc<CStr>
impl From<&mut OsStr> for Rc<OsStr>
impl From<&mut Path> for Rc<Path>

impl<T: Clone> From<&mut [T]> for Arc<[T]>
impl From<&mut str> for Arc<str>
impl From<&mut CStr> for Arc<CStr>
impl From<&mut OsStr> for Arc<OsStr>
impl From<&mut Path> for Arc<Path>
```

Since they are trait implementations, I think these are insta-stable.

As mentioned in https://github.com/rust-lang/libs-team/issues/424#issuecomment-2299415749, a crater run might be needed.

67395551d0 Auto merge of #132458 - RalfJung:rustc-const-unstable, r=Amanieu 
get rid of a whole bunch of unnecessary rustc_const_unstable attributes

In general, when a `const fn` is still unstable, it doesn't need a `#[rustc_const_unstable]` attribute. The only exception is functions that internally use things that can't be used in stable const fn yet.

So this gets rid of a whole bunch of `#[rustc_const_unstable]` in libcore.

8ccb78e0d5 Auto merge of #125579 - Noratrieb:print-host, r=davidtwco 
Add `--print host-tuple` to print host target tuple

People often parse `-vV` output to get to the host tuple, which is annoying to do. It's easier to just get it directly.

I called it "host-tuple" instead of "host" because it's clearer that it's just the target name. I'm open to different names, but I think this one is fine.

a quick GitHub search for `'^host` reveals many instances of people doing the parsing, for example:

68e0ca57cd/README.md (L369)
0e38473b0c/main.sh (L96)
8a3553b865/README.md (L625)
43f3ec3970/do.sh (L35)

needs a compiler FCP. I could also do an MCP but I think just an FCP here makes the most sense.
