/* IFBLOCK jumping algorithm
 *
 * This is easier as it looks like:
 * - each IF checks it's condition
 *   - on FALSE: call DO_JUMP
 *   - on TRUE: don't care
 * - each ELSE calls DO_JUMP unconditionally
 * - each ENDIF is silently being ignored
 *
 * Why this works:
 * DO_JUMP overwrites the "obj" variable of the loop and sets it to the target
 * (i.e. the corresponding ELSE or ENDIF). After that, processing for the given
 * object can continue, free()ing stuff e.g., then the for-loop does the rest: as
 * regularly, "obj" is being updated to point to obj->next, so object parsing
 * continues right after the corresponding ELSE or ENDIF. This means that if we
 * find an ELSE, it's corresponding IF must not have jumped, so we need to jump
 * always. If we encounter an ENDIF, it's corresponding IF or ELSE has not
 * jumped, and there is nothing to do.
