[asan] Port tests to shadow scale of 5
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.
