Rollup merge of #140208 - compiler-errors:wf-coinductive, r=lcnr 
Make well-formedness predicates no longer coinductive

This PR makes well-formedness no longer coinductive. It was made coinductive in https://github.com/rust-lang/rust/pull/98542, but AFAICT this was only to fix UI tests since we stopped lowering `where Ty:` to an empty-region outlives predicate but to a WF predicate instead.

Arguably it should lower to something completely different, something like a "type mentioned no-op predicate", but well-formedness serves this purpose fine today, and since no code (according to crater) relies on this coinductive behavior, we'd like to avoid having to emulate it in the new solver.

Fixes #123456 (I didn't want to add a test since it seems low-value to have a ICE test for a fuzzer minimization that is basically garbage code.)

Fixes #109764 (not sure if this behavior is emulatable w/o coinductive WF?)

Fixes https://github.com/rust-lang/trait-system-refactor-initiative/issues/169

README.md

This is serves as a collection of crashes so that accidental ICE fixes are tracked. This was formally done at https://github.com/rust-lang/glacier but doing it inside the rustc testsuite is more convenient.

It is imperative that a test in the suite causes an internal compiler error/panic or makes rustc crash in some other way. A test will "pass" if rustc exits with something other than 1 or 0.

When adding crashes from https://github.com/rust-lang/rust/issues, the issue number should be noted in the file name (12345.rs should suffice) and also inside the file via //@ known-bug #4321 if possible.

If you happen to fix one of the crashes, please move it to a fitting subdirectory in tests/ui and give it a meaningful name. Also please add a doc comment at the top of the file explaining why this test exists. :) Adding Fixes #NNNNN Fixes #MMMMM to the description of your pull request will ensure the corresponding tickets will be closed automatically upon merge. The ticket ids can be found in the file name or the known-bug annotation inside the testfile.

Please do not re-report any crashes that you find here!
