It's bitflags in practice, so an enum is unsound, as an enum must only have the described values. The x86_64 psABI declares it as a `typedef int _Unwind_Action`, which seems reasonable. I made a newtype first but that was more annoying than just a typedef. We don't really use this value for much other than a short check.

Add `From<{integer}>` for `f16`/`f128` impls
This PR adds `impl From<{bool,i8,u8}> for f16` and `impl From<{bool,i8,u8,i16,u16,i32,u32}> for f128`.
The `From<{i64,u64}> for f128` impls are left commented out as adding them would allow using `f128` on stable before it is stabilised like in the following example:
```rust
fn f<T: From<u64>>(x: T) -> T { x }
fn main() {
let x = f(1.0); // the type of the literal is inferred to be `f128`
}
```
None of the impls added in this PR have this issue as they are all, at minimum, also implemented by `f64`.
This PR will need a crater run for the `From<{i32,u32}>` impls, as `f64` is no longer the only float type to implement them (similar to the cause of rust-lang#125198).

document capacity for ZST as example The main text already covers this, although it provides weaker guarantees, but I think an example in the right spot does not hurt. Fixes rust-lang#80747
doc all differences of ptr:copy(_nonoverlapping) with memcpy and memmove Fixes rust-lang#79430
…, r=workingjubilee Make `_Unwind_Action` a type alias, not enum It's bitflags in practice, so an enum is unsound, as an enum must only have the described values. The x86_64 psABI declares it as a `typedef int _Unwind_Action`, which seems reasonable. I made a newtype first but that was more annoying than just a typedef. We don't really use this value for much other than a short check. I ran `x check library --target aarch64-unknown-linux-gnu,x86_64-pc-windows-gnu,x86_64-fortanix-unknown-sgx,x86_64-unknown-haiku,x86_64-unknown-fuchsi a,x86_64-unknown-freebsd,x86_64-unknown-dragonfly,x86_64-unknown-netbsd,x86_64-unknown-openbsd,x86_64-unknown-redox,riscv64-linux-android,armv7-unknown-freebsd` (and some more but they failed to build for other reasons :D) fixes rust-lang#138558 r? workingjubilee have fun

…anieu,lnicola Denote `ControlFlow` as `#[must_use]` I've repeatedly hit bugs in the compiler due to `ControlFlow` not being marked `#[must_use]`. There seems to be an accepted ACP to make the type `#[must_use]` (rust-lang/libs-team#444), so this PR implements that part of it. Most of the usages in the compiler that trigger this new warning are "root" usages (calling into an API that uses control-flow internally, but for which the callee doesn't really care) and have been suppressed by `let _ = ...`, but I did legitimately find one instance of a missing `?` and one for a never-used `ControlFlow` value in rust-lang#137448. Presumably this needs an FCP too, so I'm opening this and nominating it for T-libs-api. This PR also touches the tools (incl. rust-analyzer), but if this went into FCP, I'd split those out into separate PRs which can land before this one does. r? libs-api `@rustbot` label: T-libs-api I-libs-api-nominated
