Use sreal::nearest_int

Browse source 
Fix conversions from sreal to nearest integer.

gcc/ChangeLog:

	* cfgloop.cc (get_estimated_loop_iterations): Use sreal::to_nearest_int
	* cfgloopanal.cc (expected_loop_iterations_unbounded): Likewise.
	* predict.cc (estimate_bb_frequencies): Likewise.
	* profile.cc (branch_prob): Likewise.
	* tree-ssa-loop-niter.cc (estimate_numbers_of_iterations): Likewise
