  [Clang][OpenCL] Fix Missing `-fdeclare-opencl-builtins` When Using `--save-temps`

When compiling an OpenCL program directly with `clang` using `--save-temps`, an
error may occur if the program contains OpenCL builtins:

```
test.cl:3:21: error: use of undeclared identifier 'get_global_id'
    3 |   unsigned int id = get_global_id(0);
      |                     ^
```

This happens because the driver does not add `-fdeclare-opencl-builtins` when
the input type is `TY_PP_CL`. This PR fixes the issue.
