Absolute and relative operands on AArch64: disallow?
opnd_is_memory_ref() should check for absolute addr not only for X86_64 but for X64 overall.
opnd_create_far_abs_addr() creates relative opnd but still assigns the ABS_ADDR_kind flag to the opnd. Hence, if this function is called on aarch64, opnd_is_memory_ref() will incorrectly return false.
