int.
(end_ifcvt_sequence): Call set_used_flags on each insn in the
sequence.
Include rtl-iter.h.
(noce_simple_bbs): New function.
(noce_try_move): Bail if basic blocks are not simple.
(noce_try_store_flag): Likewise.
(noce_try_store_flag_constants): Likewise.
(noce_try_addcc): Likewise.
(noce_try_store_flag_mask): Likewise.
(noce_try_cmove): Likewise.
(noce_try_minmax): Likewise.
(noce_try_abs): Likewise.
(noce_try_sign_mask): Likewise.
(noce_try_bitop): Likewise.
(bbs_ok_for_cmove_arith): New function.
(noce_emit_all_but_last): Likewise.
(noce_emit_insn): Likewise.
(noce_emit_bb): Likewise.
(noce_try_cmove_arith): Handle non-simple basic blocks.
(insn_valid_noce_process_p): New function.
(contains_mem_rtx_p): Likewise.
(bb_valid_for_noce_process_p): Likewise.
(noce_process_if_block): Allow non-simple basic blocks
where appropriate.
