Make custom lowering of ADD work correctly. This
fixes PR2476; patch by Richard Osborne. The same problem exists for a bunch of other operators, but I'm ignoring this because they will be automagically fixed when the new LegalizeTypes infrastructure lands, since it already solves this problem centrally. llvm-svn: 52610
