	* gprof.cxx (hitcount_map_t): PC now host_int_8.
	(cg_count_map_t): Likewise.
	(statistics): value_min,value_max,limit_min,limit_max likewise.
	New member, pc_size.
	(statistics::operator=): Copy pc_size.
	(cg_caller_hi_pin): New pin.
	(cg_callee_hi_pin): New pin.
	(limit_min_set): Handle 64 bits.
	(limit_max_set): Handle 64 bits.
	(pc_size_get): New method.
	(pc_size_set): New method.
	(accumulate): Use target_attribute + "-hi" to obtain 64 bit pc. Handle
	64 bits throughout.
	(accumulate_call): Use {caller,callee}_hi pin to obtain 64 bit pc. Handle
	64 bits throughout.
	(store_stats): Handle 32 or 64 bit pc.
	(gprof_component): Add cg-caller_hi and cg-callee-hi pins. Add pc-size
	attribute. Initialize value on cg-caller-hi and cg-callee-hi to zero.
