Turns out we actually don't need it, USE_NUM_NONE works
because we also set USE_FIELD_INV_BUILTIN.

This should yield another 30-second speed up. Nobody looks
at the output of those anyway. We might want bring back gofmt later
and actually fail the build if source is not formatted.

This should decrease test runtime to about 30 seconds.
