Hi,
predict_paths_leading_to change improved coverage of heuristics based on
it. This patch updates the outcomes as well as of some other heuristics
that did change a bit over the time.
* predict.def (PRED_TREE_OPCODE_POSITIVE, PRED_TREE_OPCODE_NONEQUAL,
PRED_TREE_OPCODE_POSITIVE, PRED_TREE_OPCODE_NONEQUAL, PRED_CALL,
PRED_TREE_EARLY_RETURN, PRED_NULL_RETURN): Update.
