Fix minor things in the f32 primitive docs 
All of these were review comments in #74621 that I first fixed
in that PR, but later accidentally overwrote by a force push.

Rollup merge of #75085 - lzutao:ip_union, r=cuviper 
Transmute big endian `s6_addr` and `[u16; 8]`

The old code already made the assumption to reinterpret
`Ipv6Addr` as `[u16; 8]`.

Glibc, Linux, FreeBSD, Win32 all makes this assumption.
The main motivation of using union it to better optimize code.
Godbolt: https://rust.godbolt.org/z/b4bGvo
Const is introducing unsafe when transmuting.

a9025c571e Auto merge of #74621 - LukasKalbertodt:float-docs, r=GuillaumeGomez 
Improve `f32` and `f64` primitive documentation

I noticed that the docs for the primitive floats were fairly short. I first only wanted to add the IEEE specification information (compare [the reference](https://doc.rust-lang.org/reference/types/numeric.html)), but then also added some more beginner-friendly docs. Let me know what you think!

Rollup merge of #74200 - poliorcetics:std-panicking-unsafe-block-in-unsafe-fn, r=Mark-Simulacrum 
Std panicking unsafe block in unsafe fn

Partial fix of #73904.

This encloses `unsafe` operations in `unsafe fn` in `libstd/ffi/panicking.rs`.

I also made a two lines change to `libstd/thread/local.rs` to add the necessary `unsafe` block without breaking everything else.

ddbc45673b Add RUST_STD_FREEBSD_12_ABI env variable 
Unfortunately, sanitizers do not support versioned symbols[1],
so they break filesystem access via the legacy, pre-ino64 ABI.

To use sanitizers on FreeBSD >= 12, we need to build the libc
crate with LIBC_CI=1 to use the new ABI -- including the libc
used for std. But that removes the st_lspare field std was
expecting for the deprecated metadata extension.

Add a way to skip that field to allow the build to work.

f85d231301 clarify documentation of remove_dir errors 
remove_dir will error if the path doesn't exist or isn't a directory.

It's useful to clarify that this is "remove dir or fail" not "remove dir
if it exists".

I don't think this belongs in the title. "Removes an existing, empty
directory" is strangely worded-- there's no such thing as a non-existing
directory.  Better to just say explicitly it will return an error.

Fixes #74997.

This uses the note from the [reference](https://doc.rust-lang.org/reference/types/closure.html#call-traits-and-coercions) but I can also just put a link to it or do both.

8b26609481 Auto merge of #70052 - Amanieu:hashbrown7, r=Mark-Simulacrum 
Update hashbrown to 0.8.1

This update includes:
- https://github.com/rust-lang/hashbrown/pull/146, which improves the performance of `Clone` and implements `clone_from`.
- https://github.com/rust-lang/hashbrown/pull/159, which reduces the size of `HashMap` by 8 bytes.
- https://github.com/rust-lang/hashbrown/pull/162, which avoids creating small 1-element tables.
