Confirmed, right now we get:
  D.1711_2 = VIEW_CONVERT_EXPR<struct X>(1).y.z;
  return D.1711_2;

Confirmed again:
Before FRE:
  z = 1;
  _4 = MEM[(struct X *)&z].y.z;

Note fre we are able to do the right thing but dom does not.

------- Comment #1 from rguenth at gcc dot gnu dot org  2009-04-14 14:02 -------
Testcase for the second case:

struct Y { int z; };
struct X { struct Y y; };
int foo()
{
  int z = 1;
  struct X *x = (struct X *)&z;
  return x->y.z;
}

a testcase for the first case is harder.
