[cc2-qbe] Fix lhs() and OADDR lhs was returning the source node instead of returning the destination node, and it was hidden the error because the correct type of the lhs expression is the type of the parent when we are in a OADDR expression. Without this patch pointers passed as parameters had the same type that the base type instead of having pointer type.
