* doc/invoke.texi (Option Summary) <MN10300 Options>: Remove
redundant -mno- forms from the list.
(MN10300 Options): Combine the documentation for -mmult-bug,
-mam33, -mliw, and -msetlb with the entries for the respective
negative forms. List and index the negative forms -mno-am33-2,
-mno-am34, -mno-return-pointer-on-d0, -mno-mul.x.
