const traits: remove some known-bug that do not seem to make sense
These tests were made to point to #103507 in https://github.com/rust-lang/rust/pull/114134; I think that was a mistake: that issue is about a rather specific problem, and most tests marked as known-bug in that PR are pointing at https://github.com/rust-lang/rust/issues/110395 which makes more sense.
Of the 4 tests that still point to #103507:
- One is [the original test](2088260852/tests/ui/impl-trait/normalize-tait-in-const.rs). It still fails to compile, though currently for unrelated reasons (`~const Fn` is not valid as that is not a const trait). I made it point at #110395 like all the other tests that were disabled when the previous const trait impl was removed.
- One is being fixed in https://github.com/rust-lang/rust/pull/135423
- The other two are fixed in this PR
The errors we are getting here are not great but they do look correct?
FWIW there are still a whole lot of tests mentioning #110395 despite that issue being closed... I hope someone is tracking that.^^
