No, split_branches doesn't create helper branches for unconditional branches,
and for conditional branches, it inserts them only in places where there
is already one conditional branch to that target - inverting the condbranch
and making it jump around the helper branch.
And there is already a mechanism in place to suppress excessive alignments
for unconditional branches that are branched around.
