Reduced testcase:
```
#define vect128 __attribute__((vector_size(16)))
[[gnu::noinline]]
vect128 long f(vect128 long a)
{
return a <= (vect128 long){0, 9223372036854775807};
}
int main()
{

Slightly simplified/cleaned up testcase:
/* { dg-do run } */
/* { dg-options "-O2 -fno-vect-cost-model" } */
/* { dg-additional-options "-mavx" { target avx_runtime } } */
struct S { int a; long b; int c;

This looks wrong:
```
;; mask_patt_17.15_55 = vect_cst__53 <= { 0, 9223372036854775807 };
(insn 21 20 22 (set (reg:V2DI 111)
(mem/u/c:V2DI (symbol_ref/u:DI ("*.LC1") [flags 0x2]) [0 S16 A128]))

vectorizer generates:
mask_patt_21.19_58 = vect_perm_even_49 >= vect_cst__57;
mask_patt_21.19_59 = vect_perm_even_55 >= vect_cst__57;
vexit_reduc_63 = mask_patt_21.19_58 | mask_patt_21.19_59;
