OpenACC 2.6 deep copy: Fortran front-end parts

        gcc/fortran/
        * gfortran.h (gfc_omp_map_op): Add OMP_MAP_ATTACH, OMP_MAP_DETACH.
        * openmp.c (gfc_match_omp_variable_list): Add allow_derived parameter.
        Parse derived-type member accesses if true.
        (omp_mask2): Add OMP_CLAUSE_ATTACH and OMP_CLAUSE_DETACH.
        (gfc_match_omp_map_clause): Add allow_derived parameter.  Pass to
        gfc_match_omp_variable_list.
        (gfc_match_omp_clauses): Support attach and detach.  Support derived
        types for appropriate OpenACC directives.
        (OACC_PARALLEL_CLAUSES, OACC_SERIAL_CLAUSES, OACC_KERNELS_CLAUSES,
        OACC_DATA_CLAUSES, OACC_ENTER_DATA_CLAUSES): Add OMP_CLAUSE_ATTACH.
        (OACC_EXIT_DATA_CLAUSES): Add OMP_CLAUSE_DETACH.
        (check_symbol_not_pointer): Don't disallow pointer objects of derived
        type.
        (resolve_oacc_data_clauses): Don't disallow allocatable derived types.
        (resolve_omp_clauses): Perform duplicate checking only for non-derived
        type component accesses (plain variables and arrays or array sections).
        Support component refs.
        * trans-expr.c (gfc_conv_component_ref,
        conv_parent_component_references): Make global.
        (gfc_maybe_dereference_var): New function, broken out of...
        (gfc_conv_variable): ...here.  Call above function.
        * trans-openmp.c (gfc_omp_privatize_by_reference): Support component
        refs.
        (gfc_trans_omp_array_section): New function, broken out of...
        (gfc_trans_omp_clauses): ...here.  Support component refs/derived
        types, attach and detach clauses.
        * trans.h (gfc_conv_component_ref, conv_parent_component_references,
        gfc_maybe_dereference_var): Add prototypes.

        gcc/testsuite/
        * gfortran.dg/goacc/derived-types.f90: New test.
        * gfortran.dg/goacc/derived-types-2.f90: New test.
        * gfortran.dg/goacc/derived-types-3.f90: New test.
        * gfortran.dg/goacc/data-clauses.f95: Adjust for expected errors.
        * gfortran.dg/goacc/enter-exit-data.f95: Likewise.
