[AArch64] Add ARMv8.3 combined pointer authentication load instructions
Add support for ARMv8.3 LDRAA and LDRAB combined pointer authentication and load instructions. These instructions authenticate the base register and load 8 byte from it plus a scaled 10-bit offset with optional writeback to update the base register. A new instruction class (ldst_imm10) and operand type (AARCH64_OPND_ADDR_SIMM10) were introduced to handle the special addressing form. include/ 2016-11-18 Szabolcs Nagy <szabolcs.nagy@arm.com> * opcode/aarch64.h (enum aarch64_opnd): Add AARCH64_OPND_ADDR_SIMM10.
