Inline try_from and try_into
To avoid link time dependency between core and compiler-builtins, when using opt-level that implicitly enables -Zshare-generics.
While compiler-builtins should be compiled with -Zshare-generics disabled, the -Zbuild-std does not ensure this at the moment.

Refactor unwind in MIR
This makes unwinding from current `Option<BasicBlock>` into
```rust
enum UnwindAction {
Continue,
Cleanup(BasicBlock),
Unreachable,
Terminate,
}
```

migrate rustc_macros to syn 2.0
WIP at this point since I need to work on migrating the code that heavily uses `NestedMeta` for parsing. Perhaps a full refactor would be nice..

To avoid link time dependency between core and compiler-builtins, when
using opt-level that implicitly enables -Zshare-generics.

disabled, the -Zbuild-std does not ensure this at the moment.
* Stop checking `func` in `onEach`. It's always hard-coded right
at the call site, so there's no point.
* Use the ternary operator in a few spots where it makes sense.
* No point in making `onEach` store `arr.length` in a variable if
it's only used once anyway.
Label `non_exhaustive` attribute on privacy errors from non-local items
Label when an ADT is `non_exhaustive` and we get a privacy error, help with confusion in a case like this:
```rust
#[non_exhaustive]
pub struct Foo;
// other crate
let x = Foo;
//~^ ERROR unit struct `Foo` is private
```
Fix buffer overrun in bootstrap and (test-only) symlink_junction
I don't think these can be hit in practice, due to their inputs being valid paths. It's also not security-sensitive code, but just... bad vibes.
I think this is still not really the right way to do this (in terms of path correctness), but is no worse than it was.

diagnostics: account for self type when looking for source of unsolved type variable
Fixes#109905.
When searching for the source of an unsolved infer var inside of a list of generic args, we look through the `tcx.generics_of(…).own_substs(…)` which *skips* the self type if present. However, the computed `argument_index` is later[^1] used to index into `tcx.generics_of(…).params` which may still contain the self type. In such case, we are off by one when indexing into the parameters.
From now on, we account for this immediately after calling `own_substs` which keeps things local.
This also fixes the wrong output in the preexisting UI test `inference/need_type_info/concrete-impl.rs` which was overlooked. It used to claim that the *type of type parameter `Self`* couldn't be inferred in `<Struct as Ambiguous<_>>::method()` which of course isn't true: `Self` equals `Struct` here, `A` couldn't be inferred.

Tested all the topics mentioned above. All worked fine. The test is now also covers if build dir is manually specified in config.

Remove f32 & f64 from MemDecoder/MemEncoder
r? ```@Nilstrieb```
since they said (maybe joked) on discord that it's a bug if the compiler uses f32 anywhere 🙃
