OpenMP parallel back-end, prototype, just for discussion.

We have designed implementation of the all patterns of PSTL backend API and prototyped the first implementation for parallel_for, parallel_reduce.

“parallel_for” is based on OpenMP “task_loop”. (not parallel for to avoid oversubscription problem in case of nested parallelism)
“parallel_reduce” is based on OpenMP “task_loop” with “reduction” clause.

We would be very appreciate you (and the community in general) to get some feedback for that.
