Writing patch code to hbc

[joshuachenn]

I think it is hard to write patch code to hbc, when I added some patch code to hbc in some offset of instruction segment, the offset will be reuse in afterwards, which will cause beforehand code being modified and affect code to be disassembled incorrectly. Because added bytecode changes offset of some function.
