[PR other/70945] Handle function_glibc_finite_math in offloading

        gcc/
        PR other/70945
        * targhooks.c (default_libc_has_function): Update comment.
        * target.def (libc_has_function): Likewise.
        * doc/tm.texi: Regenerate.
        * coretypes.h (enum function_class): Add
        function_glibc_finite_math.
        * config/darwin.c (darwin_libc_has_function): Handle it.
        * lto-streamer.h (enum lto_section_type): Rename
        LTO_section_offload_table to LTO_section_offload_data.  Adjust all
        users.
        * lto-cgraph.c (void output_offload_data): New function, split out
        of output_offload_tables.  Adjust all users.  Stream the target's
        function_glibc_finite_math property.
        (input_offload_data): New function, split out of
        input_offload_tables.  Adjust all users.  Handle mismatch between
        the target's and the offloading target's
        function_glibc_finite_math property.
