1. Run with Release
2. See disasm after JIT for every public method.
3. I'm not sure if it's an issue since I know nothing with JIT, but has some questions.
   1. Why all ThrowWithCall has rep stos but not for ThrowDirect, the latter one is about 50% faster in all cases;
   2. Why when call directly into CheckIndex0ThrowWithCall, the Branch Prediction didn't work well by move throw to the end but it's well for all others;
   3. What's the different between CheckIndexThrowDirect and CheckIndexThrowDirect2, why jmp Test in the first case and call Test for the second.
