toplev.c (branch_prob_dump, [...]): New variables.

Browse Source 
* toplev.c (branch_prob_dump, profile_arc_flag, flag_test_coverage,
	flag_branch_probabilities, branch_prob_dump_file, branch_prob_time):
	New variables.
	(f_options): Add profile-arcs, test-coverage, and
	branch-probabilities.
	(compile_file): Set branch_prob_time.  Pass flag_test_coverage to
	init_emit_once.  Handle branch_prob_dump.  Call init_branch_prob.
	Call end_branch_prob. Call output_func_start_profiler.
	(rest_of_compilation): Handle branch_prob_dump.  Call new
	branch_prob pass.
	(main): Set branch_prob_dump.
