Richard Sandiford 0c608d6b62 [AArch64][SVE 20/32] Add support for tied operands 
SVE has some instructions in which the same register appears twice
in the assembly string, once as an input and once as an output.
This patch adds a general mechanism for that.

The patch needs to add new information to the instruction entries.
One option would have been to extend the flags field of the opcode
to 64 bits (since we already rely on 64-bit integers being available
on the host).  However, the *_INSN macros mean that it's easy to add
new information as top-level fields without affecting the existing
table entries too much.  Going for that option seemed to give slightly
neater code.

include/
	* opcode/aarch64.h (aarch64_opcode): Add a tied_operand field.
	(AARCH64_OPDE_UNTIED_OPERAND): New aarch64_operand_error_kind.

opcodes/
	* aarch64-tbl.h (CORE_INSN, __FP_INSN, SIMD_INSN, CRYP_INSN)
	(_CRC_INSN, _LSE_INSN, _LOR_INSN, RDMA_INSN, FP16_INSN, SF16_INSN)
	(V8_2_INSN, aarch64_opcode_table): Initialize tied_operand field.
	* aarch64-opc.c (aarch64_match_operands_constraint): Check for
	tied operands.

gas/
	* config/tc-aarch64.c (output_operand_error_record): Handle
	AARCH64_OPDE_UNTIED_OPERAND.
