Wait this should not be restricted to lp64. We really should be
warning here even if we are able to produce "correct" code. In fact I
requested this testcase when the original newer -Wstrict-aliasing
fixes was being worked on. The warning for this case was added to the
front-end so it could be optimized and still be warned about.
