test/Lower/OpenMP/delayed-privatization-reduction.f90

! Test that reductions and delayed privatization work properly togehter. Since
! both types of clauses add block arguments to the OpenMP region, we make sure
! that the block arguments are added in the proper order (reductions first and
! then delayed privatization.
