Details in the implementation of the integer 'for' loop

Changed some implementation details; in particular, it is back using
an internal variable to keep the index, with the control variable
being only a copy of that internal variable. (The direct use of
the control variable demands a check of its type for each access,
which offsets the gains from the use of a single variable.)
