[PATCH] RISC-V: Enhance AVL propagation for complicate reduction auto-vectorization

I notice we failed to AVL propagate for reduction with more complicate situation: double foo (double *__restrict a, double *__restrict b, double *__restrict c, int n) { double result = 0; for (int i = 0; i < n; i++) result += a[i] * b[i] * c[i]; return result; } vsetvli
