Debuginfo tests are serialized due to some older version of LLDB.
However, that comment was last touched in 2014, so presumably these
older versions are long since obsolete.
Partially fixes bug #72719.

Update browser-ui-test version to 0.8.2
It brings mostly debugging improvements: it doesn't stop at the first failing command but rather at the first "fatal error".

Implement -Z oom=panic
This PR removes the `#[rustc_allocator_nounwind]` attribute on `alloc_error_handler` which allows it to unwind with a panic instead of always aborting. This is then used to implement `-Z oom=panic` as per RFC 2116 (tracking issue #43596).
Perf and binary size tests show negligible impact.

GDB 11.2 added support for DW_ATE_UTF, which caused some test
failures. This fixes these tests by changing the format that is used,
and adds a new test to verify that characters are emitted as something
that GDB can print in a char-like way.

Remove redundant code from copy-suggestions
Follow up to #94375, just remove some code that is not necessary anymore. This may make the perf of such suggestions a little bit worse, but I don't think this is significant.

[generator_interior] Be more precise with scopes of borrowed places
Previously the generator interior type checking analysis would use the nearest temporary scope as the scope of a borrowed value. This ends up being overly broad for cases such as:
```rust
fn status(_client_status: &Client) -> i16 {
200
}
fn main() {
let client = Client;
let g = move || match status(&client) {
_status => yield,
};
assert_send(g);
}
```
In this case, the borrow `&client` could be considered in scope for the entirety of the `match` expression, meaning it would be viewed as live across the `yield`, therefore making the generator not `Send`.
In most cases, we want to use the enclosing expression as the scope for a borrowed value which will be less than or equal to the nearest temporary scope. This PR changes the analysis to use the enclosing expression as the scope for most borrows, with the exception of borrowed RValues which are true temporary values that should have the temporary scope. There's one further exception where borrows of a copy such as happens in autoref cases also should be ignored despite being RValues.

Stabilize ADX target feature
This is a continuation of #60109, which noted that while the ADX intrinsics were stabilized, the corresponding target feature never was.
This PR follows the same general structure and stabilizes the ADX target feature.

Make ErrorReported impossible to construct outside `rustc_errors`
There are a few places were we have to construct it, though, and a few
places that are more invasive to change. To do this, we create a
constructor with a long obvious name.

I actually didn't see that I was assigned to this issue until now...
erase late-bound regions in dyn projection types for debuginfo
simply skipping the binder leaves late-bound regions that will cause debug assertions to fail when checking the layout of the projection ty, so let's erase the regions instead.
sorry for taking so long to put this up, had trouble getting rustc set up on a new computer.
fixes#94998
* Set `config.opts.trimmed_def_paths` to `GoodPath` to trim def paths in
error messages as expected by the rustc test suite
* Fix `$SRC_DIR` normalization for out of tree compiled standard library
Fix cmake build.
This is an attempt to fix the cmake build. For some reason, it has recently started failing with a permission denied trying to overwrite `/tmp/build.log`. This file exists from the `build-toolchains.sh` step, which is owned by the rustbuild user. I think there is some behavior where a sticky `/tmp` directory doesn't allow overwriting files owned by other users even when running as root. I do not know why this has suddenly started, and I can't reproduce locally with my own docker setup. However, this fix seems to work on CI.
