Mitch Phillips 80ac0b9bc8 Fix up fuzzing test on Windows.
3bd112c720dc fixed the fuzzing test on Linux, which, after
https://reviews.llvm.org/D125933, has one less branch. Turns out, on
Windows, that it still has the extra branch. I'm guessing that's because
exit() isn't known to be noreturn on Windows or something.

Either way, just make the test more tolerant.
