Unrolled build for rust-lang#131579

Rollup merge of rust-lang#131579 - jieyouxu:ui-panic-username, r=compiler-errors

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.
