+; Check branch penalties.  It is assumed that the taken-counters
+; in the bimodal branch-predictors start at 0, meaning two taken
+; branches are required for a branch to be predicted as taken
+; for each counter, from reset.  None of these branches go
+; to the end of a cache-line and none map to the same counter.
