The tests are ported as follows: contiguous_container_crash.cc use-after-delete.cc use-after-free.cc Replace hardwired shadow granularity in CHECK statements with regex. max_redzone.cc Bump max_redzone parameter to 32. memset_test.cc Bump size parameter of __asan_poison_memory_region to 32. scariness_score_test.cc For "far-from-bounds" heap overflow, make sure overflow is more than one shadow granularity away. At large shadow granularity, there is not enough redzone between stack elements to detect far-from-bounds, so fake out that test.
