* jump.c (invert_exp_1): Remove first argument, use pc_set
to get the expression.
(redirect_exp): Make static; redirect only the pc_set expression,
remove first argument.
(invert_exp): Remove first argument, make static.
(jump_optimize): Use any_condjump_p, any_uncondjump_p and
any_onlyjump at most places where we originaly did condjump_p
and simplejump_p.
(jump_back_p, follow_jumps, thread_jumps): Likewise.
(delete_barrier_succesors): Use pc_set.
(invert_jump_1, invert_jump, redirect_jump_1, redirect_jump): Update
calls of invert_exp and redirect_exp.
* rtl.h (redirect_exp, invert_exp): Remove.
* unroll.c (copy_loop_body): Use invert_jump and redirect_jump.
