re PR middle-end/29965 (OpenMP vs always throw in a loop)
PR middle-end/29965
* omp-low.c (determine_parallel_type): Don't try to optimize combined
parallels if region->exit or region->inner->exit is NULL.
(expand_omp_parallel): Handle NULL region->exit even if cfg is already
built.
(expand_omp_for_generic): Handle NULL region->cond and region->exit.
(expand_omp_for): Use expand_omp_for_generic if either region->cond
or region->exit is NULL.
(expand_omp_sections): Handle NULL region->cond or region->exit.
(expand_omp_synch):
