Stabilize `Poll::is_ready` and `is_pending` as const
Insta-stabilize the methods `is_ready` and `is_pending` of `std::task::Poll` as const, in the same way as [PR#76198](https://github.com/rust-lang/rust/pull/76198).
Possible because of the recent stabilization of const control flow.
Part of #76225.
Use Intra-doc links for std::io::buffered
Helps with #75080. I used the implicit link style for intrinsics, as that was what `minnumf32` and others already had.

`#![deny(unsafe_op_in_unsafe_fn)]` in sys/hermit
Partial fix of #73904.
This encloses ``unsafe`` operations in ``unsafe fn`` in ``sys/hermit``.
Some unsafe blocks are not well documented because some system-based functions lack documents.
Partially fix#55002, deprecate in another release

Change as_str → to_string in proc_macro::Ident::span() docs
There is no `as_str` function on Ident any more.
Also change it to an intra doc link while we're at it.
Move Vec UI tests to unit tests when possible
Helps with #76268.
I'm moving the tests using `Vec` or `VecDeque`.

`crate::` -> `core::`
It looks weird to have `crate::` in the link text and we use the actual
crate name everywhere else.
If anyone is curious, I used this Vim command to update all the links:
%s/\(\s\)\[`crate::\(.*\)`\]/\1[`core::\2`](crate::\2)/g
Add fetch_update methods to AtomicBool and AtomicPtr
These methods were stabilized for the integer atomics in #71843, but the methods were not added for the non-integer atomics `AtomicBool` and `AtomicPtr`.
Point out that total_cmp is no strict superset of partial comparison
Partial comparison and total_cmp are not equal. This helps
preventing the mistake of creating float wrappers that
base their Ord impl on total_cmp and their PartialOrd impl on
the PartialOrd impl of the float type. PartialOrd and Ord
[are required to agree with each other](https://doc.rust-lang.org/std/cmp/trait.Ord.html#how-can-i-implement-ord).
Trivial fixes to bitwise operator documentation
Added fixes to documentation of `BitAnd`, `BitOr`, `BitXor` and
`BitAndAssign`, where the documentation for implementation on
`Vector<bool>` was using logical operators in place of the bitwise
operators.

Closes#78619
Clarify handling of final line ending in str::lines()
I found the description as it stands a bit confusing. I've added a bit more explanation to make it clear that a trailing line ending does not produce a final empty line.
These methods were stabilized for the integer atomics in #71843, but the methods
were not added for the non-integer atomics `AtomicBool` and `AtomicPtr`.
