Fix the ARM assembler to generate a Realtime profile for armv8-r.
PR 25992
gas * config/tc-arm.c : Add arm_ext_v8r feature.
(it_fsm_post_encode): Check arm_ext_v8r feature.
(get_aeabi_cpu_arch_from_fset): Check arm_ext_v8r feature.
include * opcode/arm.h (ARM_EXT2_V8R): Define. Modified ARM_AEXT2_V8R.
