    c++: fix SIGFPE with -Wclass-memaccess [PR105634]

    Here we crash because we attempt to % by 0.  Thus fixed.
    While at it, I've moved the -Wclass-memaccess tests into warn/.
    I've checked that the # of expected passes is the same before/after
    the move.

            PR c++/105634

    gcc/cp/ChangeLog:

            * call.cc (maybe_warn_class_memaccess): Avoid % by zero.
