* 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.
