Log message:
	Add support for single register window model on SPARC
	
	2011-06-27  Eric Botcazou  <ebotcazou@adacore.com>
	* sparc-tdep.h (struct sparc_frame_cache): Add frame_offset,
	saved_regs_mask and copied_regs_mask fields.
	(sparc_record_save_insn): New prototype.
	* sparc-tdep.c (sparc_alloc_frame_cache): Initialize the new fields.
	(sparc_record_save_insn): New function.
	(sparc_analyze_prologue): Add head comment.  Recognize store insns

	(sparc32_frame_cache): Adjust to new frame description.
	(sparc32_frame_prev_register): Likewise.

	* sparc-sol2-tdep.c (sparc32_sol2_sigtramp_frame_cache): Likewise.
	* sparc64-sol2-tdep.c (sparc64_sol2_sigtramp_frame_cache): Likewise.
	* sparcnbsd-tdep.c (sparc32nbsd_sigcontext_frame_cache): Force the
	frame by calling sparc_record_save_insn.
	* sparc64nbsd-tdep.c (sparc64nbsd_sigcontext_frame_cache): Likewise.
	* sparcobsd-tdep.c (sparc32obsd_sigtramp_frame_cache): Likewise.
	* sparc64obsd-tdep.c (sparc64obsd_frame_cache): Likewise.
