We support a special DefaultArgumentKind::NilLiteral, but it was only used for synthesized and imported default arguments as well. Let's also use it for parsed default arguments that are exactly 'nil', so that rethrows checking can special-case them.

// arguments are still conceptually rooted on the base declaration.

// When we call such an initializer, we have to construct substitutions

// in terms of the base class generic signature, rather than the

// derived class generic signature.
