* basic-block.h (scale_bbs_frequencies_int,

	scale_bbs_frequencies_gcov_type): Declare.
	* cfg.c (RDIV): New macro.
	(update_bb_frequency_for_threading): Fix.
	* basic-block.h (scale_bbs_frequencies_int,
	scale_bbs_frequencies_gcov_type): New.
	* cfgloopmanip.c (scale_bbs_frequencies): Kill.
	(scale_loop_frequencies, duplicate_loop_to_header_edge): Use
	scale_bbs_frequencies_int.
	* tree-ssa-loop-ch.c (copy_loop_headers): Fix profiling info.
