    Allow both signed and unsigned fields in PowerPC cmpli insn
    
    There are legitimate reasons to allow a signed value in a cmpli insn
    field, for example to test for a "stw r1,lock@sdarel(r13)" instruction
    in user code, a kernel might use
            subis r3,r3,STW_R1_0R13@ha      # subtract off high part
            cmplwi r3,lock@sdarel           # is low part accessing lock?
    Since the lock@sdarel may take a range of -32768 to 32767,
    the allowed range of cmpli immediate must be at least [-32768,65535].

            * elf32-ppc.c (ppc_elf_relocate_section): Treat field of cmpli
            insn as a bitfield; Use complain_overflow_bitfield.
            * elf64-ppc.c (ppc64_elf_relocate_section): Likewise.

            on unsigned fields.  Comment on PPC_OPERAND_SIGNOPT signed fields
            in 64-bit mode.
