Remove arm_override_mode
GDB can determine the kind of single step breakpoint by gdbarch
breakpoint_kind_from_current_state, so global variable
arm_override_mode is no longer needed. This patch removes it.
gdb:
2016-11-03 Yao Qi <yao.qi@linaro.org>
* arm-tdep.c (arm_override_mode): Remove.
(arm_pc_is_thumb): Update.
(arm_insert_single_step_breakpoint): Update.
