Otherwise `error-pattern` on the test run stderr can incorrectly match
if e.g. the paths in panic backtrace has a matching substring (like if
we look for `bar` in the error pattern but username is `baron`).
When rust-lang/rust is configured as remote, some of the git
logic (for tracking changed files) that uses get_closest_merge_commit
starts to produce annoying results as the upstream branch becomes outdated
quickly (since it isn't updated with git pull). We can rely on HEAD for
non-CI environments as we specifically treat bors commits as merge commits,
which also exist on upstream. As for CI environments, we should use
`git_upstream_merge_base` to correctly track modified files as bors commits
may be in `HEAD` but not yet on the upstream remote.

This makes the following API stable in const contexts:

    impl<T> Option<T> {
        pub const fn as_mut(&mut self) -> Option<&mut T>;
        pub const fn expect(self, msg: &str) -> T;
        pub const fn unwrap(self) -> T;
        pub const unsafe fn unwrap_unchecked(self) -> T;
        pub const fn take(&mut self) -> Option<T>;
        pub const fn replace(&mut self, value: T) -> Option<T>;
    }

    impl<T> Option<&T> {
        pub const fn copied(self) -> Option<T>
        where T: Copy;
    }

    impl<T> Option<&mut T> {
        pub const fn copied(self) -> Option<T>
        where T: Copy;
    }

    impl<T, E> Option<Result<T, E>> {
        pub const fn transpose(self) -> Result<Option<T>, E>
    }

    impl<T> Option<Option<T>> {
        pub const fn flatten(self) -> Option<T>;
    }

The following functions make use of the unstable
`const_precise_live_drops` feature:

- `expect`
- `unwrap`
- `unwrap_unchecked`
- `transpose`
- `flatten`

force "HEAD" for non-CI and `git_upstream_merge_base` for CI environment

When rust-lang/rust is configured as remote, some of the git logic (for tracking changed files) that uses get_closest_merge_commit starts to produce annoying results as the upstream branch becomes outdated quickly (since it isn't updated with git pull). We can rely on HEAD for non-CI environments as we specifically treat bors commits as merge commits, which also exist on upstream. As for CI environments, we should use `git_upstream_merge_base` to correctly track modified files as bors commits may be in `HEAD` but not yet on the upstream remote.

This is also an alternative fix for rust-lang#129528 since rust-lang#131331 reverts the previous fix attempts.

Use throw intrinsic from stdarch in wasm libunwind

Tracking issue: rust-lang#118168

This is a very belated followup to rust-lang#121438; now that rust-lang/stdarch#1542 is merged, we can use the intrinsic exported from `core::arch` instead of defining it inline. I also cleaned up the cfgs a bit and added a more detailed comment.

Remap path prefix in the panic message of `tests/ui/meta/revision-bad.rs`

Otherwise `error-pattern` on the test run stderr can incorrectly match if the paths in panic backtrace has a matching substring (like if we look for `bar` in the error pattern, but the username is `baron`).

Tested locally by checking run output `./x test .\tests\ui\meta\revision-bad.rs -- -- --nocapture`:

```
--- stderr -------------------------------
thread 'main' panicked at remapped\meta\revision-bad.rs:14:5:
foo
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
------------------------------------------
```

Fixes rust-lang#130996.
