137c3957ed [libFuzzer] add InsertRepeatedBytes and EraseBytes.
New mutation: InsertRepeatedBytes.
Updated mutation: EraseByte => EraseBytes.

This helps https://github.com/google/sanitizers/issues/710
where libFuzzer was not able to find a known bug.
Now it finds it in minutes.

Hopefully, the change is general enough to help other targets.

9906eefc84 [libFuzzer] make LLVMFuzzerTestOneInput (the fuzzer target function) return int instead of void. The actual return value is not *yet* used (and expected to be 0). This change is API breaking, so the fuzzers will need to be updated.
