* succeeding from empirical or other `hard' evidence, don't
* 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
