The illumos linker does not support --strip-debug
When building and testing rust 1.64.0 on illumos, we saw a large number of failing tests associated with:
```
= note: ld: fatal: unrecognized option '--strip-debug'
ld: fatal: use the -z help option for usage information
collect2: error: ld returned 1 exit status
```
The illumos linker does not support the `--strip-debug` option (although it does support `--strip-all`).
Remove the redundant `Some(try_opt!(..))` in `checked_pow`
The final return value doesn't need to be tried at all -- we can just
return the checked option directly. The optimizer can probably figure
this out anyway, but there's no need to make it work here.
Make diagnostic for unsatisfied `Termination` bounds more precise
Don't blindly emit a diagnostic claiming that “*`main` has an invalid return type*” if we encounter a type that should but doesn't implement `std::process::Termination` and isn't actually the return type of the program entry `main`.
Fixes#103052.

Remove "execute" bit from lock file permissions
Previously, flock would set the "execute" bit on Rust lock files. That makes no sense.
This patch clears the "execute" bit on Rust lock files.
See issue #102531.
Add `Box<[T; N]>: TryFrom<Vec<T>>`
We have `[T; N]: TryFrom<Vec<T>>` (#76310) and `Box<[T; N]>: TryFrom<Box<[T]>>`, but not this combination.
`vec.into_boxed_slice().try_into()` isn't quite a replacement for this, as that'll reallocate unnecessarily in the error case.
**Insta-stable, so needs an FCP**
(I tried to make this work with `, A`, but that's disallowed because of `#[fundamental]` https://github.com/rust-lang/rust/issues/29635#issuecomment-1247598385)

Do not register placeholder `RegionOutlives` obligations when `considering_regions` is false
**NOTE:** I'm kinda just putting this up for discussion. I'm not certain this is correct...?
This was introduced in [`608625d`](608625dae9 (diff-6e54b18681342ec725d75591dbf384ad08cd73df29db00485fe51b4e90f76ff7R361)).
Interestingly, we only check `data.has_placeholders()` for `RegionOutlives`, and not for `TypeOutlives`... why? For the record, that different treatment between `RegionOutlives` and `TypeOutlives` is why the fix "The compiling succeeds when all `'a : 'b` are replaced with `&'a () : 'b`" in #100689 _"works"_, but it seems like an implementation detail considering this.
Also, why do we care about placeholder regions being registered if `considering_regions` is false? It doesn't seem to affect any UI tests, for example.
