  [Clang][RISCV] Improve diagnostic message for full multiply intrinsics

The full multiply intrinsics are not included for EEW=64 in Zve64*.
They require the V extension to be enabled.

This commit improves diagnostic message from

```
<source>:4:10: error: call to undeclared function '__riscv_vsmul_vv_i64m1';
    4 |   return __riscv_vsmul_vv_i64m1(op1, op2, __RISCV_VXRM_RNU, vl);
```

to

```
test.c:5:10: error: builtin requires: v
    5 |   return __riscv_vsmul_vv_i64m1(op1, op2, __RISCV_VXRM_RNU, vl);
