Thanks Thomas! Pushed.

We probably wouldn’t get a speed-up that big. Even on 32-bit targets (at least
common ones), the 64-bit type and its operations (notably division) are
implemented via CPU instructions, not library calls.
At this point, the output of integers is probably bound by the many layers of
indirection of libgfortran's I/O system (which are necessary because of the
rich I/O formatting allowed by the standard).
Best,
