I think the problem is that validate_subreg etc. has a restriction like:
/* Subregs involving floating point modes are not allowed to
change size. Therefore (subreg:DI (reg:DF) 0) is fine, but

Is missing :)
Here it is:
typedef float b;
typedef b __attribute__((vector_size(16))) c;
typedef union {
c d;
b a[4];
} e;
int f;
b g[4];
void h() {
c d;
e i;
i.d = d;
f = 0;
for (; f < 4;
