+ *        make predictions.
+ *
+ *      * These are meant to be used in places that are run `a lot'.
+ *        It is wasteful to make predictions in code that is run
+ *        seldomly (e.g. at subsystem initialization time) as the
+ *        basic block reordering that this affects can often generate
