V4: Change ByteCodeHandler::startInstruction to return an enum
If ProcessInstruction is returned, the generate_* function and
endInstruction will be called. If SkipInstruction is returned, they
won't be called. This can be used by subclasses that can detect dead
code, to suppress handling that code.
