The prediction is implemented via high level predictors that used also to predict,

I will re-introduce the other predictors by followups later, this patch was
developed while looking into the gzip regression as predicting continue formed
What are the other predictors? It might help to understand it better if
we had a better overview of everything PREDICT_EXPR was going to do.
