9e6d2da83d Reduce dependence on the target name 
The target name can be anything with custom target specs. Matching on
fields inside the target spec is much more robust than matching on the
target name.

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

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.
