Rollup merge of #143159 - compiler-errors:freshen-re-error, r=oli-obk

Do not freshen `ReError`

Because `ReError` has `ErrorGuaranteed` in it, it affects candidate selection and thus causes incompleteness which leads to weirdness in eval. See the comment in the test.

Also remove an unnecessary `lookup_op_method` since it doesn't effect tests.

Fixes rust-lang/rust#132882.
