dwarf2asm.c (dw2_asm_output_offset): Use ASM_OUTPUT_DWARF_OFFSET if provided by the target. 

* dwarf2asm.c (dw2_asm_output_offset): Use ASM_OUTPUT_DWARF_OFFSET
        if provided by the target.
        (dw2_asm_output_pcrel): Likewise with ASM_OUTPUT_DWARF_PCREL.
        (dw2_asm_output_addr): New.
        * dwarf2asm.h (dw2_asm_output_addr): Declare.
        * dwarf2out.c (output_cfi): Use it for program addresses.
        (output_call_frame_info, output_die): Likewise.
        (output_aranges, output_line_info): Likewise.
