Fully support for native unwind_exit and JIT opcode handler
6e1cfea 
Now we can use native zend_unwind_exit to kill coroutines, and we no longer need to escape JIT opcode handlers check.

The most important things is we make main Coroutine be the #1 object, and its destructor will be called at first, then it will find all coroutines and to destruct them one by one, this can solve many stranger problems, otherwise, some internal object will be destructed before Coroutines (e.g. Channel), this will cause some problems.
