        * output.h (switch_to_other_text_partition): New declaration.
        * varasm.c (switch_to_other_text_partition): New function.
        * config/rs6000/rs6000.c (uses_TOC): Return 2 if
        NOTE_INSN_SWITCH_TEXT_SECTIONS is seen before finding load_toc_* insn.
        (rs6000_elf_declare_function_name): If uses_TOC returned 2, switch
        to the other text partition before emitting LCL label and switch back
        after emitting the word after it.
