`Take` is not included since users probably call it with small constants

I recommend reviewing one commit at a time, but the diff is small enough you can do it all at once if you like :)

Applied `#![deny(unsafe_op_in_unsafe_fn)]` in library/std/src/wasi

partial fix for #73904

There are still more that was not applied in [mod.rs]( 38fab2ea92/library/std/src/sys/wasi/mod.rs) and that is due to its using files from `../unsupported`

like:
```
#[path = "../unsupported/cmath.rs"]
pub mod cmath;
```

Rollup merge of #76245 - tmiasko:inline-generators, r=ecstatic-morse 
inliner: Avoid query cycles when optimizing generators

The HIR Id trick is insufficient to prevent query cycles when optimizing
generators, since merely requesting a layout of a generator also
computes its `optimized_mir`.

Make no attempts to inline functions into generators within the same
crate to avoid query cycles.

Fixes #76181.
