Don't handle unavailable/optimized-out in spu_software_single_step
When we do software single step, frame is always the innermost one, so it is impossible to get unavailable/optimized-out errors. gdb: 2016-11-11 Yao Qi <yao.qi@linaro.org> * spu-tdep.c (spu_software_single_step): Don't call get_frame_register_bytes, call get_frame_register_unsigned instead.
