	)

Parameters

loc_ref	location of the original task directive
gtid	Global Thread ID of encountering thread
new_task	task thunk allocated by __kmp_omp_task_alloc() for the ''new task''
ndeps	Number of depend items with possible aliasing
dep_list	List of depend items with possible aliasing
ndeps_noalias	Number of depend items with no aliasing
noalias_dep_list	List of depend items with no aliasing

Returns

Returns either TASK_CURRENT_NOT_QUEUED if the current task was not suspendend and queued, or TASK_CURRENT_QUEUED if it was suspended and queued

Schedule a non-thread-switchable task with dependences for execution
