Artem Dergachev 5337efc69c [analyzer] MallocChecker: Suppress false positives in shared pointers. 
Throw away MallocChecker warnings that occur after releasing a pointer within a
destructor (or its callees) after performing C11 atomic fetch_add or fetch_sub
within that destructor (or its callees).

This is an indication that the destructor's class is likely a
reference-counting pointer. The analyzer is not able to understand that the
original reference count is usually large enough to avoid most use-after-frees.

Even when the smart pointer is a local variable, we still have these false
positives that this patch suppresses, because the analyzer doesn't currently
support atomics well enough.
