<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Copy enumFrom* implementations from Int/Word for Int64/Word64

Without this, we don't get proper list fusion.

I think this sort of copying is OK for now, but we absolutely need

something better if we are going to make `IntN` use `IntN#` for all `N`.

The degree to which proper metaprogramming has been punted upon by

factoring everything through the native-sized types is disconcerting.
