* Change `InterfaceWitness` -> `ImplWitness` * Include a `SpecificId` in the `ImplWitness`. This allows the `InstBlock` it contains to have its own identity, allowing it to be changed as the impl is processed. Evaluation only updates the specific. * Create the `ImplWitness` at the start of the impl definition. In the future, this will be populated with the values of non-function associated constants. For now, it starts full of invalid instruction ids. * Implements the model suggested in #4672 . Note that the non-SemIR testdata changes are to these file: * `toolchain/check/testdata/impl/lookup/fail_todo_undefined_impl.carbon` * `toolchain/check/testdata/struct/import.carbon` * `toolchain/check/testdata/tuple/import.carbon` The last two are due to an import of generics bug exposed by this PR, which will be fixed in a follow-on. --------- Co-authored-by: Josh L <josh11b@users.noreply.github.com> Co-authored-by: Richard Smith <richard@metafoo.co.uk>
