* flags.h (flag_move_all_movables): Declare.

        (flag_reduce_all_givs): Likewise.
        * loop.c (move_movables): Handle flag_move_all_movables.
        (strength_reduce): Handle flag_reduce_all_givs.
        * toplev.c (flag_move_all_movables): Define.
        (flag_reduce_all_givs): Likewise.
        (f_options): Add -fmove-all-movables and -freduce-all-givs.
        * invoke.texi: Document new options, including alias stuff that
        wasn't included last time.
Two of the "Tooning" options :-)
