	* sidcpuutil.h (basic_cpu): Remove gprof_prev_latency. Add
	gprof_prev_cycle, gprof_unconfigured_p.
	(sample_gprof): Now takes bool argument. Compute number of samples
	based on total_insn_count + current_step_insn_count + total_latency.
	(unconfigure_gprof): Set gprof_unconfigured_p.
	(configure_gprof): Only reset gprof_pref_cycle if gprof_unconfigured_p
	is true.
	(configure): When configuring --insn-count reset gprof_prev_cycle.
