Log:

	* cfgexpand.c (expand_gimple_tailcall): Initialize profile of
	new edge.
	* ipa-inline.c (want_inline_self_recursive_call_p): Watch for missing
	profile in callgraph edge.
	* profile-count.h (apply_probability): If THIS is 0, then result is 0
	(apply_scale): Likewise.
	* tree-inline.c (copy_bb, copy_edges_for_bb, copy_cfg_body):
	Also scale profile when inlining function with zero profile.
	(initialize_cfun): Update exit block profile even when it is zero.
	* tree-ssa-threadupdate.c (clear_counts_path): Handle correctly case
	when profile is read.
