Yes, change all define_insn_and_split to that style, "TARGET_VECTOR &&
can_create_pseudo_p ()"/ "&& 1", my understanding is all those patterns

Optimize the following auto-vectorization codes:
void foo (int16_t * __restrict a, int32_t * __restrict b, int32_t c, int n)
{
for (int i = 0; i < n; i++)
a[i] = b[i] >> c;
}
Before this patch:
foo:
ble a3,zero,.L5
.L3:
vsetvli a5,a3,e32,m1,ta,ma
