+// Takes a string of IR and compiles it using LLVM's JIT Engine
+static void CreateJITFunc(const std::string &IR, CodeGenOpt::Level OLvl) {
   SMDiagnostic Err;
----------------
`CreateAndRunJITFunc` describes this better.

Please land today once you do.


================
Comment at: clang/tools/clang-fuzzer/handle-llvm/input_arrays.h:15
+#include <iostream>
+#include <string.h>
+
----------------
Are these includes needed?


================
Comment at: clang/tools/clang-fuzzer/handle-llvm/input_arrays.h:19
+static const int NumArrays = 100;
+static const int TotalSize = sizeof(int) * ArraySize * NumArrays;
+
----------------
Maybe prefix these names with `k` since they are constant.
