Parallel frontend test failures #154314
Description
#153801 introduced an option to run rustc tests with parallel compiler enabled using option --parallel-frontend-threads for tests/ui.
A number of tests are failing in that mode and were marked with //@ ignore-parallel-frontend due to more or less subtle difference in output diagnostics due to non-determinism.
This is an umbrella issue for those failures.
Some of the failures will get separate dedicated issues (or preferably just PRs with fixes) that will be linked from here.
List of the failures with reasons:
