* basic-block.h (guess_outgoing_edge_probabilities): Declare.
* cfgbuild.c (compute_outgoing_frequencies): When probability is missing,
guess it.
(find_many_sub_basic_blocks): Do update profile only when it is present.
* predict.c (set_even_probabilities): Break out from ...
(combine_predictions_for_insn): ... here; deal with !can_predict_insn_p insns.
(combine_predictions_for_bb): Use set_even_probabilities.
(bb_estimate_probability_locally): Break out from ....
(estimate_probability): ... here.
(guess_outgoing_edge_probabilities): New entry point.
