Fix desugaring of let bindings in for loops to handle continue properly
This requires putting the original loop's body inside an inner for loop
(with
the same labels as the original loop) and re-binding the temp variables in
its
"next" expression. A second flag is added to the desugared code to ensure
the
loop body executes at most once per loop.
