Split breakpoint_from_pc to breakpoint_kind_from_pc and sw_breakpoint_from_kind

Browse Source 
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.
	(arm_breakpoint_from_pc): Call arm_breakpoint_kind_from_pc
	and arm_sw_breakpoint_from_kind.
	Use GDBARCH_BREAKPOINT_FROM_PC.
	(arm_remote_breakpoint_from_pc): Call
	arm_breakpoint_kind_from_pc.
	(arm_gdbarch_init): Replace set_gdbarch_breakpoint_from_pc
	with SET_GDBARCH_BREAKPOINT_MANIPULATION.
