As said I can't reproduce this with a cross. The function is optimized way
before we get to vectorization.

this is for ppc64le. Already .fre1 has
pack (double a, double aa)
{
double u$d$0;
union u_ld u;
<bb 2>:
u.d[1] = aa_4(D);
u ={v} {CLOBBER};
return a_2(D);
}
where u is later trivially deleted as dead.
