This patch adds support for the SSBB and PSSBB speculation barrier instructions to the AArch64 assembler and disassembler.

For more details see: https://static.docs.arm.com/ddi0596/a/DDI_0596_ARM_a64_instruction_set_architecture.pdf

opcodes	* aarch64-tbl.h (aarch64_opcode_table): Add entry for
	ssbb and pssbb and update dsb flags to F_HAS_ALIAS.
	* aarch64-asm-2.c: Regenerate.
	* aarch64-dis-2.c: Regenerate.
	* aarch64-opc-2.c: Regenerate.

gas	* testsuite/gas/aarch64/system.s: Add test for ssbb
	and pssbb.
	* testsuite/gas/aarch64/system.d: Update accordingly
	and remove explicit addresses.
