Patch by Alex Duran.

It adds new task flag - detachable (bit 6, or 0x40) which can be set by compiler for a detached task;
new external entry omp_fulfill_event(), and new internal entry __kmpc_task_allow_completion_event().

Tests with samples of expected compiler codegen also provided, they use various timings of event notification versus task completion (before/after task completion, or before task start).
