[Bug rtl-optimization/14814] no folding back to ARRAY_REF for COMPONENT_REF

I should note that the tree level still cannot handle the some of this but the RTL still can do it for some 
reason.
Note after my no-lower patches what needs to be folded this time is:
*((double *)&<D1601>.e + 8B)
into
<D1601>.e[1]

Simpler example for the problem now:
struct YY {
  double &y() { return e[1]; }
  double e[3];  };

double foo(YY& r) {
return r.y();
}
double foo1(YY &r)
{
  return r.e[1];
}
The tree expressions should be the same for foo and foo1.
