cfgexpand.c (expand_gimple_tailcall): Initialize profile of new edge.
* 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.
