    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].
    
    bfd/
    	* 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.
    opcodes/
    	* ppc-opc.c (UISIGNOPT): Define and use with cmpli.
    gas/
    	* config/tc-ppc.c (ppc_insert_operand): Handle PPC_OPERAND_SIGNOPT
    	on unsigned fields.  Comment on PPC_OPERAND_SIGNOPT signed fields
    	in 64-bit mode.
    gold/
    	* powerpc.cc (relocate): Treat field of cmpli insn as a bitfield.
