[Bug middle-end/29715] New: fold produces &a - 4

[pinskia at gcc dot gnu dot org]

Take this valid testcase:
int main ()
{
  static int a[] = { 0, 1, 2 };
  int *i = a+3;
  if (i-- > a)
    return 0;
  return 0;
}

In the IR (in .orginal) we get:
  if ( --i > &a - 4B)

which is incorrect and not really defined.
