* subsegs.c (subseg_get): Accept new argument "force_new". If

    * subsegs.c (subseg_get): Accept new argument "force_new".  If
        set then a new segment is always created.  All callers changed.
        (subseg_force_new): New function.  Similar to subseg_new, but
        always force a new segment to be created.

        * config/obj-som.c (som_frob_file): Call adjust_code_sections
        for each section.
        (adjust_code_sections): New function.  Adjusts the VMA for all the
        $CODE$ subspaces.

        * config/tc-hppa.c (md_assemble): Also handle creating a fixup
        for the unwind descriptors if a function's label follows the
        .PROC and .ENTRY directives.
        (pa_entry): Don't set BSF_FUNCTION for the label symbol here; it
        is done elsewhere.  Don't create a fixup for the unwind
        descriptors if the function's label has not been defined yet.
        (pa_proc): For SOM, place each procedure within a new $CODE$
        subspace.  Adjust the segment and frag for the associated
        function label if it exists.
