AST: Add slot for substitutions for generic witnesses. If a protocol requirement is satisfied by a generic method, we'll need to save the substitutions necessary to call that method from the witness thunk. This patch adds the spot in the ProtocolConformance::Mapping to save the substitutions; for now, always leave it empty and update the code for the type change. Swift SVN r6399
