re PR libgomp/32468 (number of threads in a parallel region depends on number of SECTIONs and MAX_THREADS)
PR libgomp/32468
* omp-low.c (check_combined_parallel): New function.
(lower_omp_parallel): Call it via walk_stmts, set
OMP_PARALLEL_COMBINED if appropriate.
(determine_parallel_type): If OMP_FOR resp. OMP_SECTIONS
isn't the only statement in WS_ENTRY_BB or OMP_RETURN
the only one in PAR_EXIT_BB and not OMP_PARALLEL_COMBINED,
don't consider it as combined parallel.
* gcc.dg/gomp/pr32468-1.c: New test.
