V4: Set correct source locations for jumps out of conditionalsv5.9.0-beta1

We always want to place the jump on the last line of the conditionally
executed statement, unless we might never execute the last line.

In the latter case, that is if the inner statement is again a
conditional, we use some token of the outer condition. This works fine
with loops, as the loop condition is actually checked after each
iteration, and it's plausible to the user that we jump there.

With "if" statements, it's not so great. We cannot really explain why we
jump back to the "if" token after executing the conditional statement.
However, we have to add some source location to the jump instruction as
otherwise it uses the source location of the last statement that had
one, which is rather random.
