Auto merge of rust-lang#113621 - ehuss:ignore-clippy-tests, r=Nilstrieb

Ignore flaky clippy tests.

These tests are frequently failing due to an issue in ui_test. ui_test doesn't appear to have a blanket ignore instruction that I could find, so I just approximated it with ignoring both 32 and 64 bit.

Fixes rust-lang#113585
