2017-10-23	[libFuzzer] Periodically purge allocator's quarantine to prolong fuzzing ↵	Alex Shlyapnikov
	sessions. Summary: Fuzzing targets that allocate/deallocate a lot of memory tend to consume a lot of RSS when ASan quarantine is enabled. Purging quarantine between iterations and returning memory to OS keeps RSS down and should not reduce the quarantine effectiveness provided the fuzz target does not preserve state between iterations (in this case this feature can be turned off). Based on D39153.

2017-10-05	[libFuzzer] Disable experimental clang coverage support by default.	Max Moroz
	Summary: It can be enabled via "-use_clang_coverage=1" flag. Reason for disabling: libFuzzer resets Clang Counters and makes it impossible to generate coverage report for a regular fuzz target (i.e. not standalone build).
