Change gdbarch software_single_step frame_info to regcache

Browse Source 
This patch changes gdbarch method software_single_step's parameter from
"struct frame_info *" to "struct regcache *, IOW, software_single_step
starts to use current regcache rather than current frame for software
single.

	* gdbarch.sh (software_single_step): Change parameter from frame_info
	to regcache.
	* gdbarch.c, gdbarch.h: Regenerated.
	* aarch64-tdep.c (aarch64_software_single_step): Change parameter
	from frame_info to regcache.  Don't call get_current_regcache.
	* alpha-tdep.c (alpha_deal_with_atomic_sequence): Likewise.
	(alpha_software_single_step): Likewise.
	* alpha-tdep.h (alpha_software_single_step): Update declaration.

	* arm-tdep.c (arm_software_single_step): Likewise.
	* arm-tdep.h (arm_software_single_step): Likewise.
	* breakpoint.c (insert_single_step_breakpoint): Pass regcache to
	gdbarch_software_single_step.
	* cris-tdep.c (cris_software_single_step): Change parameter from
	frame_info to regcache.  Don't call get_current_regcache.
