           Summary: A clause consisting only of "throw" should be the
                    unlikely path

As suggested by Quirin Schroll.

  int foo(int i)
  {
    if (i)
        throw new Exception("hello");
    return i;
  }

should emit code this way:

  int foo(int i)
  {
    if (!i)
        return i;
    throw new Exception("hello");
  }

so the return statement is considered the most likely code execution path.
