    Fortran: Fix parse-dump-tree for OpenMP ALLOCATE clause
    
    Commit r14-1301-gd64e8e1224708e added u2.allocator to gfc_omp_namelist
    for better readability and to permit to use namelist->expr for code
    like the following:
      !$omp allocators allocate(align(32) : dt%alloc_comp)
        allocate (dt%alloc_comp(5))
      !$omp allocate(dt%alloc_comp2) align(64)
        allocate (dt%alloc_comp2(10))
    However, for the parse-tree dump the change was incomplete.
    
    gcc/fortran/ChangeLog:
    
            * dump-parse-tree.cc (show_omp_namelist): Fix dump of the allocator
            modifier of OMP_LIST_ALLOCATE.
