Follow-up to #11873 which moves
resolveKnownTypeWitness()
from the AST to the ClangImporter, and makes it the canonical way of resolving associated types of imported conformances, even before the type checker is torn down.Unfortunately we still rely on the type checker to resolve the
RawValue
associated type in someRawRepresentable
conformances. I think there's a logic error in ConformanceLookupTable that was previously not visible, but I haven't figured it out yet.
