    Fortran: Add location info to OpenMP tree nodes
    
    gcc/fortran/
            * trans-openmp.cc (gfc_trans_omp_critical): Set location on OMP
            tree node.
            (gfc_trans_omp_do): Likewise.
            (gfc_trans_omp_masked): Likewise.
            (gfc_trans_omp_do_simd): Likewise.
            (gfc_trans_omp_scope): Likewise.
            (gfc_trans_omp_taskgroup): Likewise.
            (gfc_trans_omp_taskwait): Likewise.
            (gfc_trans_omp_distribute): Likewise.
            (gfc_trans_omp_taskloop): Likewise.
            (gfc_trans_omp_master_masked_taskloop): Likewise.
    
    (cherry picked from commit 198bd0d599e0a91df1cfa6ab37545d05dff48e97)
