Rollup merge of #77079 - poliorcetics:more-self-in-docs, r=jyn514 
Use `Self` in docs when possible

Fixes #76542.

I used `rg '\s*//[!/]\s+fn [\w_]+\(&?self, ' .` in `library/` to find instances, I found some with that and some by manually checking.

Changing the alloc() to accept &self instead of &mut self

Fixes: [#55](https://github.com/rust-lang/wg-allocators/issues/55)

This is the first cut. It only makes the change for `alloc` method.

Avoid useless sift_down when std::collections::binary_heap::PeekMut is never mutably dereferenced

If `deref_mut` is never called then it's not possible for the element to be mutated without internal mutability, meaning there's no need to call `sift_down`.

This could be a little improvement in cases where you want to mutate the biggest element of the heap only if it satisfies a certain predicate that needs only read access to the element.

Rollup merge of #76866 - est31:master, r=lcnr 
Remove unused feature gates from library/ crates

Removes some unused feature gates from library crates. It's likely not a complete list as I only tested a subset for which it's more likely that it is unused.

Rollup merge of #76722 - ssomers:btree_send_sync, r=Mark-Simulacrum 
Test and fix Send and Sync traits of BTreeMap artefacts

Fixes #76686.

I'm not quite sure what all this implies. E.g. comparing with the definitions for `NodeRef` in node.rs,  maybe an extra bound `T: 'a` is useful for something. The test compiles on stable/beta (apart from `drain_filter`) so I bet `Sync` is equally desirable.

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 #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>>;
}
```
