* ifcvt.c (struct noce_if_info): Add rev_cond field.
(noce_reversed_cond_code): New function.
(noce_emit_store_flag): Use rev_cond if non-NULL instead of
reversed_comparison_code. Formatting fix.
(noce_try_store_flag): Test rev_cond != NULL in addition to
reversed_comparison_code.
(noce_try_store_flag_constants): Likewise.
(noce_try_store_flag_mask): Likewise.
(noce_try_addcc): Use rev_cond if non-NULL instead of
reversed_comparison_code.
(noce_try_cmove_arith): Likewise. Formatting fixes.
(noce_try_minmax, noce_try_abs): Clear rev_cond.
(noce_find_if_block): Initialize rev_cond.
(find_cond_trap): Call noce_get_condition with then_bb == trap_bb
instead of false as last argument never attempt to reverse it
afterwards.
