Re: enforce (i > 0) for i = int.min does not throw

This is insane. i > 0 is used in so many places. The only 
saving grace appears to be that int.min is just so uncommonly 
seen in the wild.

And another one that it does not happen when compiled with 
optimization (-O) and also that it does not affect all the ints:

---
import std.stdio;

void foo (T) ()
{
   auto i = T.min;
   writefln ("%12s: %24X %12s", T.stringof, i, i > cast(T) 0);
}

void main ()
{
   foo!byte;
   foo!short;
   foo!int;
   foo!long;
}

        byte:                       80        false
       short:                     8000        false
         int:                 80000000         true
        long:         8000000000000000         true

In 32 bit mode:

        byte:                       80        false
       short:                     8000        false
         int:                 80000000         true
        long:         8000000000000000        false
