Rollup of 8 pull requests - #158661

in `tests/ui/consts/const-eval/raw-bytes.rs` as we now handle this in
our modified regex in `runtest`

Specifically, all `//@ ignore-parallel-frontend different alloc ids`

across other tests because they fail with our
normalization strategy: `ALLOC0` -> `ALLOC$ID`

Fixes test failures on {aarch64*-none, armv7r-eabihf, thumbv7em-eabi*} targets which
have panic=abort by default

…nstantiate_identity().skip_norm_wip().def_id

The starting point of this commit is that `ModuleData`, `ImportData`,
and `DeclData` are all interned, and don't need to be `Clone`.

Then there are various types nestled within these types that also don't
need to be `Clone`.

Three of the four public allocation functions in `DroplessArena` check
that the allocated type doesn't implement `Drop`: `alloc`,
`alloc_slice`, `alloc_from_iter`. This commit adds the missing check to
`try_alloc_from_iter`.

It also moves and reorders some lines in `alloc_from_iter` for
consistency with the other methods.

Fixes rust-lang#158388,
as per T-libs-api decision there.

Implement clamp_to

Implements the revised version of rust-lang#147781. Supersedes rust-lang#147786.

Currently I restrict the ClampBounds trait using a second, perma-unstable feature. I don't know if that's the usual way to deal with this kind of traits, I'd be happy to change it if not.

~~I currently define NaN as equal to no bound. This is consistent with `max` and `min`, but is inconsistent with `clamp`, which panics.~~

Changed so that the float versions panic if any bound is NaN, just like `clamp` does.

tests: fix: parallel frontend test failures: different alloc ids

Removed the `//@ ignore-parallel-frontend different alloc ids` directive from all the ui tests applicable and replaced it with `//@ normalize-stderr` so that all alloc ids mentions are converted into a single placeholder. Thus the tests are passed

delegation: support simplest output `Self` mapping

This PR supports simplest output `Self` mapping for callee path if the following conditions are met (see `should_wrap_return_value`).

Example:
```rust
trait Trait {
    fn method(&self) -> Self;
    fn r#static() -> Self;
    fn raw_S(&self) -> S { S }
}

struct S;
impl Trait for S {
    fn method(&self) -> S { S }
    fn r#static() -> S { S }
}

struct W(S);
impl Trait for W {
    #[attr = Inline(Hint)]
    fn method(self: _) -> _ { Self { 0: Trait::method(self.0) } }
    #[attr = Inline(Hint)]
    fn r#static() -> _ { Trait::r#static() }
    //~^ WARN: function cannot return without recursing [unconditional_recursion]
    #[attr = Inline(Hint)]
    fn raw_S(self: _) -> _ { Trait::raw_S(self.0) }
}

impl W {
    #[attr = Inline(Hint)]
    fn method(self: _) -> _ { Self { 0: Trait::method(self.0) } }
    #[attr = Inline(Hint)]
    fn r#static() -> _ { Trait::r#static() }
    #[attr = Inline(Hint)]
    fn raw_S(self: _) -> _ { Trait::raw_S(self.0) }
}

```

~If the above conditions are met, there is no need to propagate generics of a newtype, as unused generics is an error, thus they should be used in a single field and it can be inferred from the return type of callee path.~

~Accessing signatures through queries produced query cycles in one test, so `with_no_trimmed_paths` was used to prevent it, though it can cause other cycles in other situations maybe.~

Fix getrandom fallback test on platforms with `panic=abort`

The recently-added linux-getrandom-fallback test fails on targets matching {aarch64*-none, armv7r-eabihf, thumbv7em-eabi*}. This is because those platforms set `panic=abort` by default, and the test relies on being able to catch a panic.

Mark the test as `needs-unwind` so that it won't be run in `panic=abort` configurations.

Also add extra debug information to the panic when getrandom() fails with an unexpected error code on Linux
