    Add support for storing args during an exception raised by an irq. · 5b7fd20f

    The user code should call micropython.alloc_emergency_exception_buf(size)
    where size is the size of the buffer used to print the argument
    passed to the exception.
    With the test code from #732, and a call to
    micropython.alloc_emergenncy_exception_buf(100) the following error is
    now printed:
    >>> import heartbeat_irq
    Uncaught exception in Timer(4) interrupt handler
    Traceback (most recent call last):
      File "0://", line 14, in heartbeat_cb
    NameError: name 'led' is not defined
