7ff17c13bc Rollup merge of #76910 - lcnr:foreign-item-like, r=oli-obk 
transmute: use diagnostic item

closes #66075, we now have no remaining uses of `match_def_path`  in the compiler while some uses still remain in `clippy`.

Remove unused feature gates from library/ crates

Removes some unused feature gates from library crates. It's likely not a complete list as I only tested a subset for which it's more likely that it is unused.

b873fa6d42 Auto merge of #76136 - CDirkx:const-result, r=dtolnay 
Stabilize some Result methods as const

Stabilize the following methods of Result as const:
 - `is_ok`
 - `is_err`
 - `as_ref`

A test is also included, analogous to the test for `const_option`.

These methods are currently const under the unstable feature `const_result` (tracking issue: #67520).
I believe these methods to be eligible for stabilization because of the stabilization of #49146 (Allow if and match in constants) and the trivial implementations, see also: [PR#75463](https://github.com/rust-lang/rust/pull/75463) and [PR#76135](https://github.com/rust-lang/rust/pull/76135).

Note: these methods are the only methods currently under the `const_result` feature, thus this PR results in the removal of the feature.

5ef1db3622 Revert adding Atomic::from_mut. 
This made too many assumptions about platforms, breaking some things.

Will need to be added later with a better way of gating on proper
alignment, without hardcoding cfg(target_arch)s.

fef3324043 Rollup merge of #76492 - fusion-engineering-forks:int-bits, r=dtolnay 
Add associated constant `BITS` to all integer types

Recently I've regularly come across this snippet (in a few different crates, including `core` and `std`):
```rust
std::mem::size_of<usize>() * 8
```

I think it's time for a `usize::BITS`.

1720fd94e8 Rollup merge of #76434 - RalfJung:black-box, r=Mark-Simulacrum 
do not inline black_box when building for Miri

We cannot do the assembly trick in Miri, but let's at least make sure MIR inlining does not circumvent the black_box.

Also use black_box instead of local optimization barriers in a few const tests.
