/* The *_start routines are called when first encountering a loop construct
that is not bound directly to a parallel construct. The first thread
that arrives will create the work-share construct; subsequent threads
will see the construct exists and allocate work from it.
START, END, INCR are the bounds of the loop; due to the restrictions of
OpenMP, these values must be the same in every thread. This is not
verified (nor is it entirely verifiable, since START is not necessarily
retained intact in the work-share data structure). CHUNK_SIZE is the
scheduling parameter; again this must be identical in all threads.
Returns true if there's any work for this thread to perform. If so,
*ISTART and *IEND are filled with the bounds of the iteration block
allocated to this thread. Returns false if all work was assigned to
other threads prior to this thread's arrival. */
