LGTM with a nit



================
Comment at: lib/Fuzzer/FuzzerMutate.h:146
   std::vector<uint8_t> MutateInPlaceHere;
+  // Custom CrossOver needs own buffer as implementation can call
+  // LLVMFuzzerMutate which can resize MutateInPlaceHere.
----------------
CustomCrossOver needs its own buffer as a custom implementation may call
LLVMFuzzerMutate, which in turn may resize MutateInPlaceHere
