* sanopt.c (maybe_get_single_definition): New function.
(maybe_get_dominating_check): Ditto.
(can_remove_asan_check): Ditto.
(struct tree_map_traits): New struct.
(struct sanopt_ctx): Use custom traits for asan_check_map.
(maybe_optimize_ubsan_null_ifn): Move code to
maybe_get_dominating_check.
(maybe_optimize_asan_check_ifn): Move code and take non-SSA expressions
into account when optimizing.
(sanopt_optimize_walker): Optimize ASan checks even when
recovering.
