...as Solaris is missing flock()

fixes rust-lang#103630

The was careful around not calling `fn_sig` on not-functions but well,
it wasn't careful enough. This commit makes it a little more careful and
also adds tests for a bunch more item kinds.

Stabilize `atomic_as_ptr`

Fixes rust-lang#66893

This stabilizes the `as_ptr` methods for atomics. The stabilization feature gate used here is `atomic_as_ptr` which supersedes `atomic_mut_ptr` to match the change in rust-lang#107736.

This needs FCP.

New stable API:

```rust
impl AtomicBool {
    pub const fn as_ptr(&self) -> *mut bool;
}

impl AtomicI32 {
    pub const fn as_ptr(&self) -> *mut i32;
}

// Includes all other atomic types

impl<T> AtomicPtr<T> {
    pub const fn as_ptr(&self) -> *mut *mut T;
}
```

r? libs-api
``@rustbot`` label +needs-fcp

use `as_ptr` to determine the address of atomics

The PR rust-lang#107736 renamed  atomic `as_mut_ptr` to `as_ptr`. Consequently, the futex implementation of the tier-3 platform `RutyHermit` has to use this new interface. In addition, this PR removes also an unused import.

Treat projections with infer as placeholder during fast reject in new solver

r? ``@lcnr``

Kind of a shame that we need to change all of the call sites for `for_each_relevant_impl`, etc. to pass an extra parameter. I guess I could have the "default" fn which calls a configurable fn?

simd-wide-sum test: adapt for LLVM 17 codegen change

Gracefully handle `#[target_feature]` on statics

The was careful around not calling `fn_sig` on not-functions but well, it wasn't careful enough. This commit makes it a little more careful and also adds tests for a bunch more item kinds.

I was sadly not able to fully bless the test locally because I'm on an aarch64 machine but I hope some manual editing made it work 😅
