* config/tc-xtensa.c (xg_force_frag_space): Delete.

        (xg_finish_frag, xg_assemble_literal_space): Replace calls to it.
        (xtensa_create_property_segments, xtensa_create_xproperty_segments):
        Set output_section for new property sections.  Use subseg_set and
        seg_info instead of retrieve_segment_info.  Adjust arguments to
        add_xt_block_frags and add_xt_prop_frags.  Use standard functions
        to create frags and fix records.
        (retrieve_segment_info): Delete.
        (add_xt_block_frags, add_xt_prop_frags): Replace calls to
        retrieve_segment_info.  Remove unused xt_block_sec arguments.
