Probably better (more regular) like this:

if (Target->shouldSplitToVariableVecOn32(Ty)) {
  Var = VariableVecOn32::create(this, Ty, Index);
} else if (Target->shouldSplitToVariable64On32(Ty)) {
  Var = Variable64On32::create(this, Ty, Index);
} else {
  Var = Variable::create(this, Ty, Index);
}

Done.
