Rollup merge of rust-lang#110004 - SparrowLii:failure_status, r=oli-obk

add `dont_check_failure_status` option in the compiler test

Sometimes the compiler triggers one ice while processing another ice. This will cause a recursive panic and go to [`sys::abort_internal()`](https://github.com/rust-lang/rust/blob/master/library/std/src/panicking.rs#L675), which generates an unfixed exit code. So I think we need an option to allow these use cases to generate different exit codes

Updates rust-lang#75760
cc rust-lang#95134

For example, when set `parallel_compiler = true`, issue-95134 will ice in `report_ice` since it try to print the query stack. Below is the brief error message:
```
