The problem is the follow if is being hit:
2941          /* If OP is a constant that has overflowed, do not value number
2942             this expression.  */
2943          if (CONSTANT_CLASS_P (op)
2944              && TREE_OVERFLOW (op))

Which means we don't get a VH correctly for this statement.
