Split breakpoint_from_pc to breakpoint_kind_from_pc and sw_breakpoint_from_kind
We convert each ARCH_breakpoint_from_pc to ARCH_breakpoint_kind_from_pc
and ARCH_sw_breakpoint_from_kind. Note that gdbarch doesn't have methods
breakpoint_kind_from_pc and sw_breakpoint_from_kind so far.
gdb:
2016-11-03 Yao Qi <yao.qi@linaro.org>
* arch-utils.h (GDBARCH_BREAKPOINT_FROM_PC): New macro.
(GDBARCH_BREAKPOINT_MANIPULATION_ENDIAN): New macro.
* arm-tdep.c (arm_breakpoint_from_pc): Remove.
(arm_breakpoint_kind_from_pc): New function.
(arm_sw_breakpoint_from_kind): New function.

and arm_sw_breakpoint_from_kind.
Use GDBARCH_BREAKPOINT_FROM_PC.
