/// you can specify that Ss is equivalent to
///   NSt3__112basic_stringIcNS_11char_traitsIcEENS_9allocatorIcEEEE
/// and then manglings that refer to libstdc++'s 'std::string' will be
/// considered equivalent to manglings that are the same except that they refer
/// to libc++'s 'std::string'.
///
/// This can be used when data (eg, profiling data) is available for a version
/// of a program built in a different configuration, with correspondingly
/// different manglings.
