This uses search_for_cycle_permutation to look for variances_of in case variances_of is not the first query in the cycle.

This may fix #124423 and #127971.

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.
