21a17d105c support in-place iteration for most adapters 
`Take` is not included since users probably call it with small constants
and it doesn't make sense to hold onto huge allocations in that case

0f122e1119 add in-place iteration for Zip 
this picks the left hand side as source since it might be more natural to

Respect -Z proc-macro-backtrace flag for panics inside libproc_macro 
Fixes #76270

Previously, any panic occuring during a call to a libproc_macro method
(e.g. calling `Ident::new` with an invalid identifier) would always
cause an ICE message to be printed.

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

1e33c742ca Auto merge of #75971 - Amjad50:libstd-deny-unsafe_op_in_unsafe_fn, r=Mark-Simulacrum 
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;
```

559679b8c3 Applied #![deny(unsafe_op_in_unsafe_fn)] in library/std/src/wasi

in `alloc` method to satisfy the SAFETY statement

Rollup merge of #76243 - ama0:patch-1, r=jonas-schievink 
Fix typos in vec try_reserve(_exact) docs

`try_reserve` and `try_reserve_exact` docs refer to calling `reserve` and `reserve_exact`.
`try_reserve_exact` example uses `try_reserve` method instead of `try_reserve_exact`.

@jyn514 We're almost finished with this issue. Thanks for mentoring. If you have other topics to work on just let me know, I will be around in Discord.

Rollup merge of #76204 - NoraCodes:nora/control_flow_enum, r=scottmcm 
Rename and expose LoopState as ControlFlow

Basic PR for #75744. Addresses everything there except for documentation; lots of examples are probably a good idea.
