Adds this import line::
from builtins import (ascii, bytes, chr, dict, filter, hex, input,
int, list, map, next, object, oct, open, pow,
range, round, str, super, zip)
to a module, irrespective of whether each definition is used.
Adds these imports after any other imports (in an initial block of them).
