Mark helper regs defined in final_tidyup before freeres_wrapper call.
In final_tidyup we setup the guest to call the freeres_wrapper, which
will (possibly) call __gnu_cxx::__freeres() and/or __libc_freeres().
In a couple of cases (ppc64be, ppc64le and mips32) this involves setting
up one or more helper registers. Since we setup these guest registers
we should make sure to mark them as fully defined. Otherwise we might
see spurious warnings about undefined value usage if the guest register
happened to not be fully defined before.
This fixes PR402006.
