[libFuzzer] Report at most one crash per input.
Summary:
Fixes https://github.com/google/sanitizers/issues/788/, a deadlock
caused by multiple crashes happening at the same time. Before printing
a crash report, we now test and set an atomic flag. If the flag was
already set, the crash handler returns immediately.
