tv-reddy ad65be829e cpu: update info related direction into BP if mispredicted. 
Update direction info of a branch into BP if, the branch is not
found in the target buffer. Therefore, this  updated direction is
used to squash the branch later on. Previously, some mispredicted
branches were not sqaushed as the BP had old info.
