- This patch adds support for thread_limit clause on target directive according to OpenMP 51 [2.14.5]
- The idea is to create an outer task for target region, when there is a thread_limit clause, and manipulate the thread_limit of task instead. This way, thread_limit will be applied to all the relevant constructs enclosed by the target region.
