target-s390x: PER successful-branching event support
For the PER successful-branching event support, we can't rely on any
QEMU infrastucture. We therefore call an helper in all places where
a branch can be taken. We have to pay attention to the branch to next
case, as it's still a taken branch.
We don't need to care about the cases using goto_tb, as we have disabled
them in the previous patch.
