RISC-V: Fix vector tuple intrinsic

Consider this following case:
void test_vsoxseg3ei32_v_i32mf2x3(int32_t *base, vuint32mf2_t bindex, vint32mf2x3_t v_tuple, size_t vl) {
  return __riscv_vsoxseg3ei32_v_i32mf2x3(base, bindex, v_tuple, vl);
}

Compiler failed with:
test.c:19:1: internal compiler error: in vl_vtype_info, at config/riscv/riscv-vsetvl.cc:1679
