Pass list of defineable opaque types into canonical queries This eliminates `DefiningAnchor::Bubble` for good and brings the old solver closer to the new one wrt cycles and nested obligations. At that point the difference between `DefiningAnchor::Bind([])` and `DefiningAnchor::Error` was academic. We only used the difference for some sanity checks, which actually had to be worked around in places, so I just removed `DefiningAnchor` entirely and just stored the list of opaques that may be defined. fixes #108498 fixes https://github.com/rust-lang/rust/issues/116877 * [x] run crater - https://github.com/rust-lang/rust/pull/122077#issuecomment-2013293931 |
