Hi,
since all uses of those functions are now updated to profile counts and probabilities,
we can rmeove these.

Bootstrapped/retested x86_64-linux, comitted.

	* cfg.c (scale_bbs_frequencies_int,
	cale_bbs_frequencies_gcov_type): Remove.
	* cfg.h (scale_bbs_frequencies_int,
	cale_bbs_frequencies_gcov_type): Remove.
