int.min behaves weirdly

[cbuttner]

fn void int_min() {
  io::printn(int.min); // Prints -2147483648
  io::printn((float)int.min); // Prints positive 2147483648.0
  assert(int.min == -2147483648); // Assert violation
  assert((float)int.min == -2147483648.0f); // Assert violation
}

Fixed, thank you!
