Clean up some suspicious code. There's no guarantee a constant of integer type is a ConstantInt, so it's not safe to just cast<> these to ConstantInt. (It could be a constant expression, for example) The code is shorter this way too :).

bool got() { return true; }
extern(C) int printf(char*, ...);
void main()
{
  bool b = true && got();
  printf("%d\n", b ? 1 : 0);
}
