New omp_all_memory task dependence type is implemented.

Library recognizes the new type via either 
(dependence_address == NULL && dependence_flag == 0x80 (set highest bit of 1-byte flag)) 
or 
(dependence_address == SIZE_MAX).

A task with new dependence type depends on each preceding task with any dependence type (kind of a dependence barrier).
