this is the the bytecode i generate
```
for ( ;; )
    if ( foo() )
        return bar();

main:
    code:
        block_0:
            br block_1
        block_1:
            br block_2
        block_2:
            r0 = call_cmethod com.meduzik.Main.foo this
            r1 = to_bool r0
            condbr r1 block_3 block_4
        block_3:
            r2 = call_cmethod com.meduzik.Main.bar this
            ret r2
        block_4:
            br block_1



for ( ; cond(); )
    if ( foo() )
        return bar();
