[cfe-dev] Driver interaction with -fsanitize=memory

[dvyukov]

Hi,

Please also include tsan into this plan (and probably asan?). Tsan does not
need to see all memory accesses, but it needs to see all synchronization.
Some atomic-operation-based synchronization in shared_ptr is compiled into
libstdc++ and causes false positives:
