stall interface can be implemented by objects that also
implement the cycle and step interfaces. The
stall interface controls the addition of extra cycles between
steps.
The get_stall_cycles function returns the remaining number of stall cycles. The object will advance that number of cycles before starting with the next step.
The set_stall_cycles function is used to change the number of stall cycles before the next step. It is legal to first call this function with a large value for cycles and then at a later point reduce the cycle count is resume execution earlier than indicated by the first call.
The get_total_stall_cycles returns the total accumulated number of stall cycles.

cycles_t (*get_stall_cycles)(conf_object_t *obj);
