Add a SPECIAL declaration to quiet ACL compiler.
Added IGNORE declaration.
Added a terse PRINT-METHOD for MT-RANDOM-STATE objects when *PRINT-READABLY* is nil.

Always printing these structures readably eats huge numbers of lines unnecessarily.
Document the argument to MAKE-MT-RANDOM-STATE.
Added MAKE-LOAD-FORM method for MT-RANDOM-STATE.

Makes structure literals compile-able.
