   * Old CidrSwitchBuilder is unable to deal with options with spaces embedded. This is a hack to
   * preserve the old behaviour for 2016.3 Original hack explanation: - this list of switches is
   * currently only used in one place -- GCCCompiler.tryRunGCC. - list is written to an argument
   * file, whitespace-separated, then passed as a @file arg to clang. In this context, escaped
   * whitespace within a single arg is not handled. Currently, the only way (short of using
   * reflection) to ensure unescaped whitespace is to have CidrSwitchBuilder treat whitespace as a
   * delimiter between args.
