This optimizations turns
loop {

if (cond1) {
if (cond2) {
do_work_1();
break;
} else {
do_work_2();
}
do_work_3();
break;
} else {

}
}
into:
loop {
...
if (cond1) {
if (cond2) {
do_work_1();
} else {
do_work_2();
do_work_3();
}
break;
} else {

}
}
As this optimizations moves code into the NIF statement,
it re-iterates on the branch legs in case of success.
