Note even though the optimization was in GCC 11+ (r11-2550-gca2b8c082c4f added
it), only GCC 13+ hits it in this case as GCC 13 lowers the vector comparison
and uses the scalar for the one element signed 64

With -fwrapv:

Well the cvise reduced testcase is undefined code:

__tuple_element_t<__i, tuple<_Elements...>> get(tuple<_Elements...>) {
double __trans_tmp_23{};
double *__trans_tmp_21 = &__trans_tmp_23;
