[Bug tree-optimization/45522] VRP misses oppurtunity for statement folding.

[hubicka at gcc dot gnu dot org]

------- Comment #6 from hubicka at gcc dot gnu dot org  2010-09-03 20:12 -------
In testcase from comment #4 the problem is that value in DECL_INITIAL is not in
the form acceptable for gimple_min_invariant.  Have patch.
In testcase from comment #5 we never try to fold it.
