1.0.21.24: saving runtime options in executables

 * SAVE-LISP-AND-DIE argument :SAVE-RUNTIME-OPTIONS causes the values
   of --dynamic-space-size and --control-stack-size used in the
   current invocation of SBCL to be saved in the executable core, which
   will then reuse them instead of doing normal runtime option processing.

 * Thanks to Zach Beane.
