----------------
[we discussed this a few times before]
We do not allow system includes in asan/tsan/msan/sanitizer_common  files (other than OS-specific ones).
This rule does not have to be followed in dfsan, but you have been warned  -- using stddef/stdint in sanitizers may cause you PAIN while porting to non-linux.
And you may easily avoid these headers.
