    Fortran: Add send_to_remote [PR107635]

    Refactor to use send_to_remote instead of the slow send_by_ref.

    gcc/fortran/ChangeLog:

            PR fortran/107635

            * coarray.cc (move_coarray_ref): Move the coarray reference out
            of the given one.  Especially when there is a regular array ref.
            (fixup_comp_refs): Move components refs to a derived type where
            the codim has been removed, aka a new type.
            (split_expr_at_caf_ref): Correctly split the reference chain.
            (remove_caf_ref): Simplify.
            (create_get_callback): Fix some deficiencies.
            (create_allocated_callback): Adapt to new signature of split.
            (create_send_callback): New function.
            (rewrite_caf_send): Rewrite a call to caf_send to
            caf_send_to_remote.
            (coindexed_code_callback): Treat caf_send and caf_sendget
            correctly.
            * gfortran.h (enum gfc_isym_id): Add SENDGET-isym.
            * gfortran.texi: Add documentation for send_to_remote.
            * resolve.cc (gfc_resolve_code): No longer generate send_by_ref
            when allocatable coarray (component) is on the lhs.
            * trans-decl.cc (gfc_build_builtin_function_decls): Add
            caf_send_to_remote decl.
            * trans-intrinsic.cc (conv_caf_func_index): Ensure the static
            variables created are not in a block-scope.
            (conv_caf_send_to_remote): Translate caf_send_to_remote calls.
            (conv_caf_send): Renamed to conv_caf_sendget.
            (conv_caf_sendget): Renamed from conv_caf_send.
            (gfc_conv_intrinsic_subroutine): Branch correctly for
            conv_caf_send and sendget.
            * trans.h: Correct decl.

    libgfortran/ChangeLog:

            * caf/libcaf.h: Add/Correct prototypes for caf_get_from_remote,
            caf_send_to_remote.
            * caf/single.c (struct accessor_hash_t): Rename accessor_t to
            getter_t.
            (_gfortran_caf_register_accessor): Use new name of getter_t.
            (_gfortran_caf_send_to_remote): New function for sending data to
            coarray on a remote image.

    gcc/testsuite/ChangeLog:

            * gfortran.dg/coarray/send_char_array_1.f90: Extend test to
            catch more cases.
            * gfortran.dg/coarray_42.f90: Invert tests use, because no
            longer a send is needed when local memory in a coarray is
            allocated.
