[MIPS/GAS] Split Loongson CAM Instructions from loongson3a

bfd/
	* elfxx-mips.c (print_mips_ases): Add CAM extension.

binutils/
	* readelf.c (print_mips_ases): Add CAM extension.

gas/
	* NEWS: Mention Loongson Content Address Memory (CAM)
	support.
	* config/tc-mips.c (options): Add OPTION_LOONGSON_CAM and
	OPTION_NO_LOONGSON_CAM.
	(md_longopts): Likewise.
	(mips_ases): Define availability for CAM.
	(mips_convert_ase_flags): Map ASE_LOONGSON_CAM to
	AFL_ASE_LOONGSON_CAM.
	(mips_cpu_info_table): Add ASE_LOONGSON_CAM for loongson3a.
	(md_show_usage): Add help for -mloongson-cam and
	-mno-loongson-cam.
	* doc/as.texi: Document -mloongson-cam, -mno-loongson-cam.
	* doc/c-mips.texi: Document -mloongson-cam, -mno-loongson-cam,
	.set loongson-cam and .set noloongson-cam.
	* testsuite/gas/mips/loongson-3a-2.d: Move cam test to ...
	* testsuite/gas/mips/loongson-cam.d: Here.  Add ISA/ASE
	flag verification.
	* testsuite/gas/mips/loongson-3a-2.s: Move cam test to ...
	* testsuite/gas/mips/loongson-cam.s: Here.
	* testsuite/gas/mips/loongson-3a-mmi.d: Add ASE flag.
	* testsuite/gas/mips/mips.exp: Run loongson-cam test.

include/
	* elf/mips.h (AFL_ASE_LOONGSON_CAM): New macro.
	(AFL_ASE_MASK): Update to include AFL_ASE_LOONGSON_CAM.
	* opcode/mips.h (ASE_LOONGSON_CAM): New macro.

opcodes/
	* mips-dis.c (mips_arch_choices): Add CAM to loongson3a
	descriptors.
	(parse_mips_ase_option): Handle -M loongson-cam option.
	(print_mips_disassembler_options): Document -M loongson-cam.
	* mips-opc.c (LCAM): New macro.
	(mips_opcodes): Replace IL2F|IL3A marking with LCAM for CAM
	instructions.
