* basic-block.h (EDGE_FREQUENCY): New macro.
* bb-reorder (fixup_reorder_chain): Set counts and frequencies
for new BB/edges.
* flow.c (find_sub_basic_blocks): Likewise.
(try_crossjump_to_edge): Likewise; use EDGE_FREQUENCY
(redirect_edge_and_branch): Use EDGE_FREQUENCY.
* predict.c (DEF_PREDICTOR): New argument FLAGS.
(HITRATE): New macro.
(PRED_FLAG_FIRST_MATCH): New constant.
(predictor_info): New field flgags.
(combine_predictions_for_insn): Use DS theory to combine
probabilities; set the edge probabilities when finished.
(estimate_probability): Avoid duplicated matches
of LOOP_BRANCH heuristics for nested loops; update comment.
* predict.def: Add flags for each prediction, set probabilities
according to B&L paper.
* predict.h (DEF_PREDICTOR): New argument FLAGS.
* profile.c (compute_branch_probabilities): Cleanup way the edge
probabilities are computed and REG_BR_PROB notes are dropped; if
values does not match, emit error.
(init_branch_prob): Do error instead of warning when profile driven
feedback is missing or corrupt.
