[Bug c++/35766] Should cast pointers and references more efficiently and safely

[pinskia at gcc dot gnu dot org]

I get a branchless form with -march=i686 -O2:
        testl   %edx, %edx
        leal    4(%edx), %ecx
        cmovne  %ecx, %eax


Also in your case if d is NULL, then b has to be NULL.  Nothing to do with
anything else
