These tests were failing rarely on my MacBook when there was some
activity in the background. Read: one of a thousand executions?
* sections.c missed the sorting based on thread ids. This worked
as long as the master thread finished its section before the
worker thread started the second one but failed if the master
thread was put to sleep by the OS.
* The checks in single.c assumed that the master thread executes
the single region which works most of the time because it is
usually faster than the newly spawned worker thread.

The code is tested to work with latest clang, GNU and Intel compiler. The implementation
is optimized for low overhead when no tool is attached shifting the cost to execution with
tool attached.
This patch does not implement OMPT for libomptarget.
