Move sparc opcode hwcaps out of sparc_opcode flags field.

Move sparc opcode hwcaps out of sparc_opcode flags field.

include/opcode/

	* sparc.h (struct sparc_opcode): New field 'hwcaps'.
	F_MUL32, F_DIV32, F_FDMULD, F_V8PLUS, F_POPC, F_VIS, F_VIS2,
	F_ASI_BLK_INIT, F_FMAF, F_VIS3, F_HPC, F_RANDOM, F_TRANS,
	F_FJFMAU, F_IMA, F_ASI_CACHE_SPARING, F_HWCAP_MASK): Delete.
	(HWCAP_MUL32, HWCAP_DIV32, HWCAP_FSMULD, HWCAP_V8PLUS, HWCAP_POPC,
	HWCAP_VIS, HWCAP_VIS2, HWCAP_ASI_BLK_INIT, HWCAP_FMAF,
	HWCAP_VIS3, HWCAP_HPC, HWCAP_RANDOM, HWCAP_TRANS, HWCAP_FJFMAU,
	HWCAP_IMA, HWCAP_ASI_CACHE_SPARING, HWCAP_AES, HWCAP_DES,
	HWCAP_KASUMI, HWCAP_CAMELLIA, HWCAP_MD5, HWCAP_SHA1,
	HWCAP_SHA256, HWCAP_SHA512, HWCAP_MPMUL, HWCAP_MONT, HWCAP_PAUSE,
	HWCAP_CBCOND, HWCAP_CRC32): New defines.

opcodes/

	* sparc-opc.c (sparc_opcodes): Rework table to put HWCAP values
	into new struct sparc_opcode 'hwcaps' field instead of 'flags'.

gas/

	* config/tc-sparc.c (sparc_arch_table): Rework to use HWCAP_*
	masks.
	(sparc_md_end): No longer need to translate hwcap_seen values into
	ELF hwcap bits, they now match exactly.
	(get_hwcap_name): Use HWCAP_* and handle new values.
	(sparc_ip): Fetch hwcaps from insn->hwcaps instead of insn->flags.
