Implementation of OpenMP 5.0 mutexinoutset task dependency type.

Authored by AndreyChurbanov on Oct 17 2018, 10:54 AM.



Added new type of task dependency. Library expects from compiler to use value 4 as a mutexinoutset dependency type (1 is for in, 3 is for out and inout, so it is logically to have next bit for the new type). For each depend object library creates mutex (up to 4 in total, this is heuristic limit that can be changed in future if needed). Setting of mutexes added to Task Scheduling Constraint conditions. Task with mutexinoutset dependencies can be scheduled only if all mutexes it needs are successfully set.

Any comments are welcome.
