Review Comment:
nit: Will we create this variable before function body in global scope?
If yes, then why we need this indent before `const sampler_t ...`?
I suppose it should be something like that:
```
const sampler_t image_sampler = "CLK_NORMALIZED_COORDS_FALSE |
CLK_ADDRESS_CLAMP | CLK_FILTER_NEAREST;\n";
__kernel void kernel_name(..) {
// ...
}
```
Am I right?
