Rollup merge of #132583 - mejrs:tuples, r=compiler-errors 
Suggest creating unary tuples when types don't match a trait

When you want to have a variadic function, a common workaround to implement this is to create a trait and then implement that trait for various tuples. For example in `pyo3` there exists
```rust
/// Calls the object with only positional arguments.
pub fn call1(&self, args: impl IntoPy<Py<PyTuple>>) -> PyResult<&PyAny> {
   ...
}
```

with various impls like
```rust
impl<A: IntoPy<PyObject> IntoPy<Py<PyAny>> for (A,)
impl<A: IntoPy<PyObject, B: IntoPy<PyObject> IntoPy<Py<PyAny>> for (A, B)
... etc
```

This means that if you want to call the method with a single item you have to create a unary tuple, like `(x,)`, rather than just `x`.

This PR implements a suggestion to do that, if applicable.

Rollup merge of #132559 - bvanjoi:fix-132534, r=compiler-errors 
find the generic container rather than simply looking up for the assoc with const arg

Fixes #132534

This issue is caused by mismatched generic parameters. Previously, it tried to find `T` in `trait X`, but after this change, it will find `T` in `fn a`.

r? `@compiler-errors`  as this assertion was introduced by you.

Rollup merge of #132544 - dianne:unstable-library-feature-backticks, r=compiler-errors 
Use backticks instead of single quotes for library feature names in diagnostics

This PR changes the text of library feature errors for using unstable or body-unstable items. Displaying library feature names in backticks is consistent with other diagnostics (e.g. those from `rustc_passes`) and with the `reason`s on unstable attributes in the library. Additionally, this simplifies diagnostics when supporting multiple unstable attributes on items (see #131824) since `DiagSymbolList` also displays symbols using backticks.

432972cae6 Auto merge of #132275 - compiler-errors:deref-effects, r=fee1-dead 
Register `~const` preds for `Deref` adjustments in HIR typeck

This doesn't *do* anything yet, since `Deref` and `DerefMut` aren't constified, and we explicitly don't error on calling non-const trait methods in HIR yet -- presumably that will wait until std is re-constified. But I'm confident this logic is correct, and this (afaict?) is the only major hole left in enforcing `~const` in HIR typeck.

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.

Also remove the unused is_builtin target spec field.

Add bad-reg inline assembly ui test for RISC-V and s390x

https://github.com/rust-lang/rust/pull/131341#discussion_r1826555431

> Btw, such unsupported registers are present in most architectures, but only aarch64/arm64ec, x86_64, and not yet merged [sparc/sparc64](https://github.com/rust-lang/rust/pull/132472/files#diff-02aebda3376c2b020265137f9ce2c387669ca5cfecd7d60494275c2387db5114) (and powerpc/powerpc64 by this PR) currently have ui tests for them.  I plan to add tests for other arches later.

Starting with RISC-V and s390x, which I'm familiar with and relatively easy to check for correctness.

(Relevant rustc code are supported_types/def_regs/overlapping_regs in [compiler/rustc_target/src/asm/riscv.rs](588a420350/compiler/rustc_target/src/asm/riscv.rs) and [compiler/rustc_target/src/asm/s390x.rs](588a420350/compiler/rustc_target/src/asm/s390x.rs).)

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.

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.

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.

rustdoc: skip stability inheritance for some item kinds

For some item kinds it's incorrect to inherit their parent's stability, because they might be accessible without referring to the parent directly -- This PR removes the stability inheritance for these items and reverts their displayed stability to that before https://github.com/rust-lang/rust/pull/130798.

Impl items, both inherent and trait impls, have a stability, but it is ignored when checking for enabled features. However, impl items are automatically unstable if they're nested inside an unstable module -- this caused the children of impl to inherit the instability and lead to https://github.com/rust-lang/rust/issues/132440.

Furthermore, for associated items only the stability of the associated item itself is checked and not that of its parent impl. This is true even for trait impls and we have [relied on this behavior in the standard library in the past](https://doc.rust-lang.org/1.37.0/std/slice/trait.SliceConcatExt.html#tymethod.concat), so these also shouldn't inherit the impl's stability.

I've also removed the stability inheritance for primitives and keywords so that viewing e.g. [the `i32` docs on `core`](https://doc.rust-lang.org/nightly/core/primitive.i32.html) will no longer show "since 1.6.0". Note that we currently don't annotate stability for the keyword docs, but if we start doing so in the future then this is probably more correct.
