BTreeMap: wrap node's raw parent pointer in NonNull

Now that the other `*const` (root) is gone, seemed like a small step forward.

Rollup merge of #76525 - fusion-engineering-forks:string-drain, r=dtolnay 
Add as_str() to string::Drain.

Vec's Drain recently [had its `.as_slice()` stabilized](https://github.com/rust-lang/rust/pull/72584), but String's Drain was still missing the analogous `.as_str()`. This adds that.

Also improves the Debug implementation, which now shows the remaining data instead of just `"Drain { .. }"`.

Rollup merge of #76492 - fusion-engineering-forks:int-bits, r=dtolnay 
Add associated constant `BITS` to all integer types

Recently I've regularly come across this snippet (in a few different crates, including `core` and `std`):
```rust
std::mem::size_of<usize>() * 8
```

I think it's time for a `usize::BITS`.

Rollup merge of #76434 - RalfJung:black-box, r=Mark-Simulacrum 
do not inline black_box when building for Miri

We cannot do the assembly trick in Miri, but let's at least make sure MIR inlining does not circumvent the black_box.

Also use black_box instead of local optimization barriers in a few const tests.

Rollup merge of #76310 - scottmcm:array-try_from-vec, r=dtolnay 
Add `[T; N]: TryFrom<Vec<T>>` (insta-stable)

This is very similar to the [existing](https://doc.rust-lang.org/nightly/std/convert/trait.TryFrom.html#impl-TryFrom%3CBox%3C%5BT%5D%3E%3E) `Box<[T; N]>: TryFrom<Box<[T]>>`, but allows avoiding the `shrink_to_fit` if you have a vector and not a boxed slice.

Like the slice equivalents of this, it fails if the length of the vector is not exactly `N`.
This uses `Vec<T>` as the `Error` type to return the input, like how the `Rc<[T]> -> Rc<[T; N]>` (and Arc) ones also reflect the input directly in the error type.

```rust
#[stable(feature = "array_try_from_vec", since = "1.47.0")]
impl<T, const N: usize> TryFrom<Vec<T>> for [T; N] {
    type Error = Vec<T>;
    fn try_from(mut vec: Vec<T>) -> Result<[T; N], Vec<T>>;
}
```

a0925fba74 Auto merge of #76790 - ssomers:btree_slice_slasher_returns, r=Mark-Simulacrum 
BTreeMap: avoid slices even more

Epilogue to #73971: it seems the compiler is unable to realize that creating a slice and `get_unchecked`-ing one element is a simple fetch. So try to spell it out for the only remaining but often invoked case.

Also, the previous code doesn't seem fair game to me, using `get_unchecked` to reach beyond the end of a slice. Although the local function `slice_insert` also does that.
