Alex Shlyapnikov 028c4cddad [Sanitizers] New sanitizer API to purge allocator quarantine. 
Summary:
Purging allocator quarantine and returning memory to OS might be desired
between fuzzer iterations since, most likely, the quarantine is not
going to catch bugs in the code under fuzz, but reducing RSS might
significantly prolong the fuzzing session.
