I turn the default vec_reassoc_width to 2 but find no new failed test. But the
case will trigger the spill. I think this is a possible side effect of the
reassoc
optimization. Given that vector loads/stores are quite expensive, we should be
careful when increasing vec_reassoc_width in the future.
```
/* option: -O3 -march=rv64gcv -mabi=lp64d -mrvv-vector-bits=zvl */
typedef unsigned char v128qi __attribute__ ((vector_size (128)));
v128qi
sum4 (const volatile v128qi *p)
{
v128qi hold1 = p[4];
v128qi hold2 = p[5];
v128qi sum = p[0] + p[1] + p[2] + p[3];
return (sum ^ hold1) - hold2;
}
```
