…trochenkov Do not use ImplDerivedObligationCause for inherent impl method error reporting We were constructing a `TraitRef` out of impl substs, for an *inherent* impl that has no corresponding trait. Instead of doing that, let's construct a meaningful obligation cause code, and instead adjust the error reporting machinery to handle that correctly. Fixes rust-lang#110131 cc rust-lang#106702, which introduced this regression
