Auto merge of #145384 - ywxt:parallel-tests, r=jieyouxu
Add more tests for the parallel rustc At the moment, the parallel frontend test cases are severely lacking. Althought some reported issues have been resolved, they haven't been added into the tests. This PR arranges the resolved ICE issues and adds tests for them. Whether it is worthwhile to add a separate test suite for the paralel frontend still requires futher discussion. But we are trying coveraging issues being resolved through capability of the existing UI test suite. Discussion: [Zulip](https://rust-lang.zulipchat.com/#narrow/channel/233931-t-compiler.2Fmajor-changes/topic/Proposal.20for.20a.20dedicated.20test.20suite.20for.20t.E2.80.A6.20compiler-team.23906) Related issues: - rust-lang/rust#120760 - rust-lang/rust#124423 fixed by rust-lang/rust#140358 - rust-lang/rust#127971 fxied by rust-lang/rust#140358 - rust-lang/rust#120601 fixed by rust-lang/rust#127311 cc `@jieyouxu`
