  Changed paths:
    M compiler-rt/test/fuzzer/minimize_crash.test

  Log Message:
  -----------
  minimize_crash.test sometimes one-shots the minimization (fix flaky test)

After 223470 it is now possible for minimize_crash to one-shot the minimization
by applying the EraseBytes mutation 3 times (to go from size 8=>4=>2=>1).
